Worked for me, thank you 
Seems like it doensāt work for those who bought DLC 1 :C
any news? Iām with the exactly same error.
Well I did explain problem, and said that I did everything that was here and so on in my support ticket. You know what IMC support staff did? They told me to take a look for solution in this threadā¦ Itās like they didnāt even take a look at ticket, and auto reply was used.
Sad man, is because they dont have a answer.
For me worked: I just disabled the DLC so entered in the game, I dont tested if the Levels gained are real, but I played with my character.
Oh and when you disable, check on the ādownload management of Steamā because the game will update instantly", before lauch the game.
Of course when they changed the values of the DLCs on Steam something was wrong and everybody was affected, principal the ones who took pac1 first, the lower in cost (not proposital).
Try it and tell me if worked.
Danm i can log in inside game but im getting stock at server selection says those who buy dcl pack has intant access and those who not need to wait 30 days. which it sucks 
I notice on the Server Status page, 3 of the servers are ācrowdedā. Does that mean that aside from people posting on this thread, everyone else is able to log-in?
I am still unable to log-in, every time I run the client it just gets stuck running in the background.
Iām still having issues. Iāve done all of these and still get an error on the patcher.
I was able to get on this morning, and just like an hour ago, now itās giving me the update failed issue again.
still not working. tsk tsk
I was playing the game from 9:30pm until 10pm EDT, then my game crashed after I pressed N and now Iām unable to play again.
First I got the Update Error, did everything in this post, now the client doesnāt give me any feedback (thereās just that load popup) of what is going on and I canāt play!!!
Still havenāt done daily neither dungeons -_-
can we start getting real possible solutions to fix this? The problem comes back everytime i restart my computer 
It is just sad that the admin or the management shows little care to us founders. Weāll for me this is a matter they cannot neglect. why? because we paid for the early access. A day that we canāt play means that weāre not getting the worth of our money.
2 days not being able to log-in, I hope thereās a fix before the weekend.
i copy this from my indonesian forum i hope this work to all of youā¦ mine workā¦ credit and anything in that forum postā¦ 
lol that hyperlink blend with normal wordā¦
Yeah, wait 1 week more and you can play for free! The $9.99 tier 3 dlc is non-existent at the moment.
I managed to play a few hours ago. Then Iām back on the āWeāve finished updatingā¦ Please try running the game client againā loop. GG wp.
For people who have āupdate fail, pls restart againā problem. Here is my solution:
1.Uninstall TOS and delete āTreeOfSaviorā from your Steam/Steamapps/common.
2.Reinstall the game again and then DO NOT launch 1st.
3.Restart your pc and open ur tos.exe as admin from Steam/Steamapps/common/treeofsavior/release/patch.
4.Here you go, enjoy.
PS: I meet this problem twice and I did this solution and everything go smooth. Hope it helps~ 
Thanks! I have updated but get this error, and did what u said, downloaded 5 Files again, and worked without step 2 and 3. just step 1
nope itās pushed back to may.
