Got this error few days ago, tried all the solution in the forum but no avail…
Now it came out only 2 errors which what I know is from tos.exe and client_tos.exe (which links to mscrv100.dll)
screenshot… I gave up, try troubleshooting from 6pm till 5am nothing seems get to work.
Worked for my friend. Sharing your solution to the public.
there’s some process thats interfering with tos, find it stop it or remove it, it will work
make a new user account run tos, if it runs, alt tab open task manager take a screenshot of all running processes at that moment,
go back to the old use account, run tos, it crashes, open task manager compare with the screen shot u took from before and remove the extra processes, do make sure to test running tos after removal of every process to nail down the culprit
Verify the integrity of cache in steam, if that doesnt work, uninstall, redownload, reinstall
Any Help???
i need solve this problem
Here i got the same error, but it occurs when trying to use an hability that requires a shield without having one equiped (with peltasta class) =/
Ahhhh! I also have the Client_Exe error as well!!!
When I press start, the game starts up as a white screen and maybe even progresses into a black screen… and it looks like it’ll start okay, but soon after about 10 seconds, the “Client.tos.exe has stopped working” notification window pops up and forces me to close the game before the server selection screen even appears! I’ve been trying to deal with this for the past few days using the following methods in this order:
I cannot obtain an error log about this either… 
I tried installing and playing the game on another newer computer, but the same problem pops up too, and I did the same list of things for that computer too.
Does anyone have an idea what I should do?!?!?! I’m at my wit’s end here!!!
You really need to read all the above posts
read system requirement before posting error, if your hardware don’t get enough to run the game, don’t force it and report something like this to admin. there is no way to fix these thing unless they should ask Korean developer to rebuild the game back to be used by low hardware
I wouldn’t be posting here if I hadn’t read all the above posts beforehand for the past 5 days and found a solution that worked for me. I’ve also attempted to utilize solutions from this topic that I did not list in my previous post as well. I apologize for saying this, but please don’t wave me off with a lazy answer that doesn’t attempt to help at all. I also apologize for sounding desperate and annoying, but I really am trying to find a working solution here. And yes, it could be just a problem on their side that I’d have to wait for them to fix, but I’m hoping it is not so and am still trying to possibly resolve this problem.
Also, I of course read the system requirements before posting the error as well. I’ve confirmed with others that are currently playing the game that both my computers (the older one and the newer one) should be able to at least play the game on minimum required settings.
So before any incoming flames, does anyone have any other helpful ideas on what I should do?
I fixed mine by deleting the .xml files
I corrupted them somehow…
Have you tried running it on a new user, or a fresh windows install with the bare minimum drivers, graphics, sound etc (just the bare minimum in them as well, like HydraDm comes bundled with ATI graphic Drivers)
Do not look for just HydraDm, you wont find it if you don’t have a ATI Drivers, it could be anything.
Also if its just a few people with this problem, don’t get your hopes up on them fixing it anytime soon, i don’t see it being on top of their list of priorities, after all the game is running on hundreds of other PC’s, the problem could most likely be on your end as it was on ours.

got this same error today 11/4/2015, this definitely works. if you cant kill the process just try restarting your PC. tho what I did to fix the error was verify the game cache on steam
ironic that every time they give out a patch to address the last error/bug, a new one appears!
i think the problem lies on the “luncher downloader/patcher” as it looks like its having a hard time downloading/ organizing files.
this worked for me ha! THANK YOU!
Thank You T^T this work for me 
TRIED deleting the processes as said earlier but not working!!! please help…

i have the sme error since the last week mantainence. i dont know what can i do. plz help.
click TOS’s play button on steam then wait for the "Client_tos.exe has stopped working " errorthen dont click the “close program” option just close the window then click play again on steam if the error comes up again play it then dont wait for the error message to pop up what you gonna do is right click on task bar >go to start task manager find tos.exe>right click on it>click end process tree then play it again if there’s no error message pops up just wait for it and it will go to server selection.
just redo play>end process until no error message .
as for me i only do it twice and it will go through. HOPE IT HELPS
