So ever since I installed some good looking Minecraft Village mod, it messed up my WAW game. Most modded maps that used to work before stopped working and so did any new map I installed. I've deleted all of my installed mods from Cod WAW, verified Cod WAW's game files, I've even uninstalled then re-downloaded Cod WAW but nothing seems to fix it. The map I'm trying to play now is Abandoned School. All of my other friends can play it solo and co-op without a problem but I can't try either without getting the 'Unhandled  Expectation Caught' on the Cod WAW console after I try to start the map up. I've tried so much from lowering my voice quality to 44100 Hz quality, typing in logfile 1 on the commands and pretty much anything else I can find on the Internet

Could really do with some help. Thank you in advance.

Did everyone in your group install and/or uninstall t4m?
Maybe there is a mismatch between versions.

if your on windows 7 or better
right-click the codwaw.exe go to compatibility and set it to Windows XP Service Pack 2 or 3
this may help i had same prob this was my fix
the cause of my problem may have been different
