I tried every fix I could:
Restart the game.
Quit wemod and steam and all process
try it in steam (works great)
launch steam the Alt-tab (to wemod, doesnt launch it)
Remove the cache.
Remove the leveldb ’ folder
Restart the machine
Check the files integritu in steam (ok)
Launch several other games (no problem)
Try and to automatically or manually remove it from the wemod list (none of the fixes work).
