(adsbygoogle = window.adsbygoogle || []).push({}); Every time i try to start up GTA4 i keep getting the 'Corrupted Data' message.

I have tried uninstalling all data related to GTA4 and i still keep on getting the error..
I can't restore the system as my brother and sister have an account on it with data that is to much for my USB to store, which prevents me from backing the data up.

Any suggestions on how i can solve this problem?

just delete the game data save data ect ect and reinstalll it

When i go onto 'Game Data', it's not there..
