Sure i would be glad to help, but I will need some more info on your end.
What OS are you running
what public hack are you trying to install?
Do you have all the proper .dll's
it may be simply the pub you are trying to use is patched,
ill take a shot by asking you to try MPGH menu pub. AWESOME!
(if any of this helped click that THANKS button
any questions feel free to PM me
hope to help
