Dump_wmimmc.sys BSOD

ok so each time i wanna run crossfire i first runned it, it said crossfire.exe stopped working,tried twice, i got a blue screen of Dump_wmimmc.sys and when my comp came back i tried again, i got another blue screen of death of Dump_wmimmc.sys and idk why i keep gettin these....i searched bout it, it said its a error in the gameguard or something. the files inside "GameGuard" folder are
*CrossFireUS.ini *npgmup.des.new
*GameGuard.des *npgmup.erl
*GameGuard.ver *npsc.des
*GameMon.des *Splash.jpg
*ggscan.des
*npgg.erl
*npgg9x.des
*npggNT.des
*npgl.erl
*npgm.erl
*npgmup.des

if anyone knows what to do to fix this blue screen of death it would be nice...
