If the game just crashes that means that the hack is detected or patched. This hack will no longer work for anyone.
Please remember, hacks are patched because you cheat.
NEGATIVE!! If he's using XP then thats most likely his problem. Does NOT mean the hack is patched nor does it mean it wont work for anyone. Alot of these same PUBs that are being released simply aint working for most XP users.
