Bio-Hazzard

Now nearly every time I play BF2 after about 10 minutes or so i get a authentication client kick Does anyone know what this is and better still how to fix it would be nice

i have been playing on game arena servers for a while now and the other day i got banned for using a hack after futher checking i found out that the hack that i use for a file sharing program (azureus) to slow my uploads was mistaken for a hack on battlefield 2 so eveyone be warned when useing the azureus hack at the same time as playing a PB protected game i just hope that PB unbans me at least i have support of the ranked server that i got the ban in that has to count for somthing
