That has not worked for me.   

I just posted about the same thing.  I get the exact same error.  I've also run as admin, but it still happens. 

I've found that whenever playing lvl 6 or lvl 11 I always disconnect and get an error.  I've played those lvls many times over and found that  everytime this happens when fighting CodeRed.  Sometimes it happens the moment he comes on screen.  Other times its when I have him close to death, but it always happens before I manage to get him down. 
The error I receive:
ASSERT FAILED!!!

Program : C:\Zylon Gaming\BoutCheetah\bout.dat
File : f:\boutAU3/4*\oopa\source\engine\monstermanager.cpp
Line : 1457

Experssion:
(m_MonsterData[m_MonsterAiInfo[m_MonsterLocalInfo[monster_id].monster_aiinfo].imgIndex].MonGenAniInfo.AniFrames[MA_JUMP]/2)!=0

Unfortunately it would not allow me copy+paste the error, so the part after "File : f:\boutAU" is a little off as I could not make the true characters.  After AU is the 3/4 fraction as a single character.  Next the * is a division sign.  oopa is actually a small circle, an accented o, a "u" with a tail like a p, then an accented a.  I've uninstalled boutcheetah then reinstalled it, but this did not help.  Any help will be appreciated.  Thx in advance.
