1.Do you have the firmware for it?2.What games-some cards need patching for certain games3.You posted in the wrong section, just because it's a "general" issue, doesn't mean it goes in general discussion, try technical help next time.

Prehaps...Are they still in rar/7zip format?Need to uncompress themPrehaps the downlaods were corrupted prehaps?Not sure otherwise...
