I noticed some sources for the Vitality crack as being wrong, which is really a multiplier, its a binary that runs itself in the memory then opens itself up again, closing the first, then the 2nd opens itself again, and then closes and this continues.
So make sure if you do use a crack, get from a good source.
By a good source? So you are telling us we will get different types of cracks?
If I didn't get you wrong, how come the crack form ViTALiTY be any different in different sites?
And yes, that "multiplier" seems to be an effective way of thwarting hacks/cheats/trainers, etc.
