I keep getting this Cvar message: Server Disconnected. Has been kicked via PunkBuster for 0 minutes – Cvar r_alllowextensions = (=0).

Please, can anyone help with this? Thanks!

That could be an issue with a modified, tampered, or corrupted PunkBuster cvar file. I recommend reinstalling both WET and TCE. If the problem persists try to download WET from a different mirror.

ok many servers run league configs and said configs are designed to make more fair and equal game play some servers use this on their public but to connect before you connect in server type /r_allowExtensions "1"
you can also highlight and copy that strand and in console press ctrl+v and it will copy an other one changed on servers is /r_lodCurveError "0" since its in league and follow same steps

omg xeno stop telling ppl to reinstall for cvar kicks....lol

if ppl get kicked for a cvar, all they have to do is see what the kick was for, and then change the cvar to accommodate the server....when u connect to a server, pull down ur console, it will tell u the cvar ranges allowed for the server... also usually u will be given a warning before u are kicked, make note of the range at that time in order to change it.
