Hi, I had a nasty bug with the game client.
I tried to eliminate all the methods described in this forum (client reinstallation, downloaded files). The very interesting in all this is sometimes (well, rarely) the client is launched, it can happen every few days, rest of the time I get an error.
did you tried doing the local cache verification thingy?_?
Hi @abcfox7, Kindly try this workaround.
- Right click on Tree of Savior (English Ver.)
- Click on Properties
- Click Local Files tab
- Click Verify Integrity of Game Cache
If the issue still persist, please let us know. Thanks 
This is the first thing I did. Today, the game starts after you reinstall , but after some time she again stopped running . It’s a shame to play 3 hours , I need to re-install the game client .
sorry for my English
When pressed during boot patcher pops up this error. Exploring steam on this issue came across a lot of people who have this problem,my morality play this game less and less with each passing day.
I had that happen to my before,but it solved on it own or cant remember what I did 
don’t give up and keep trying to enter…
