Hi @raknoelclaude,

Kindly submit a ticket to the Tree of Savior support team to further assist you regarding the matter.

If you uninstalled the game via steam menu, there may be some files leftover. You should manually delete the ToS folder inside steam folder.
Regarding this error, I suggest you to run the game client integrity verification. It will check and replace corrupted files. After this process, your game should be able to run normally.

thank you for ur replies. Ive already submitted a ticket to the support team.
Also. I have been able to launch the game yesterday after the 1h maintenance. But today I got the same proble, again even after re installing the game. So maybe anyone having the same issue as me managed to fix it?
I get 5 pop up boxes like in the picture








It is weird because I don’t get this bug. It would be better if I can take a look at your game client via teamviewer to see what I can do. The final option should be uploading my current game client so you can download and replace.

hey thanks again for the fast reply, how do I use teamviewer? also waiting for the staff reply on my last ticket just in case they figured out how I can fix it
