[M. Bison]

I tried this method over a freshly extracted aviara v71 , my client keeps crashing now. Pulling down a different version of cs to test with.

I tried again with a v70 game, ran the nosteam.ru v71 patch, then applied bison's fix. I can join the server for about 2 seconds then my client crashes.

Hmmm... Looks like the platform files were updated too. Try copying all of this into /counter-strike source/ (it should show hl2.exe in the folder)

If that doesn't work, perhaps try running game as administrator (win7/vista)?  ???

NOT eve one server working.until you find a solution for your servers I will not update patch.Other servers from Server browser working.

try in rev ini :
AllowOldRev=True
or
AllowUnknown=True

bir3yk broke backwards compatibility. those servers must be running the older v70 fix. iirc, AllowUnknown caused server instability and bir3yk recommends not using it. I'll need to get someone to test whether AllowOldRev works.
