I will keep tagging this on to the end of this thread until someone with greater powers than me, namely God or the System Administer of this forum comes up with a genuine fix.
I have tried EVERYTHING in these threads and the ONLY thing that works is this workaround below for my OLD Pentium 4 PC with XP, is to follow this when the punkbuster error appears (Heartbeat or Communication)..... - Open task manager (ctrl+alt+delete).
- Click on the Applications tab.
- Right Click "QUAKE LIVE - Windows Internet Explorer" (substitute for Firefox)
- Click Go to Process
- Right Click IEXPLORE.EXE (Substitute for Firefox)
- Set Priority Low
I hope this works for some of you!
