that could be it, at that all computers when anticheat didn't worked i had
ESET.NOD32.v2.50.25 [Polish] trial with some NOD32.FiX.v1.9-nsane.exe crack
at that one computer [ mine, where r1q2 worked just fine ]
and imon from that nod32 didnt check update.ini or i'm blind
So, when someone got that problem, just use winsockxpfix, or update Your nod32..
