[HELP!] Ground Zero Hack

I have a problem:

When i play with the Ground Zero Hack is all O.K. but when I play with some maps I'm falling through the maps, although I aushab Ghost Mode.

It is at these maps:

Square, Old Moon, Hyperium, Galleon, Neoniac

I do not know if it is in other maps. I can not remember it:)

Sry for this bad english:( Google is a bad tranlate:(
