Since 2 days, each time I play a map with mapmixer (installed since many time without any trouble until theses days),

at the end of a match, when I clic on "back on menu" button, the game crash.

this is a part of the log :

Critical: appError called:

I have checked, the file KernelBase.dll is still on this folder....

WTF is that?

(I have already delete all ShaderCache.upk in case of, but still crash...)

Have you already encounter this trouble with mapmixer actually?
