Unresolved 360rev freezing

ok ive got 360rev and the program will freeze whenever i try to get it to open mu usb, heres what ive done

1.I do have the correct .net framework 4
2.ive made sure that my usb was correctly configured to xbox 360 standards
3.tried opening it in 360rev with admin mode turned off without compatability mode
4.tried opening it in 360rev with admin mode turned off with compatability mode (all versions)
5.tried opening it in 360rev with admin mode turned on without compatability mode
6.tried opening it in 360rev with admin mode turned on with compatability mode (all versions)

No matter what the program will freeze, but when i remove the usb the program will unfreeze and continue to run.

i dunno what the problem is, any suggestions?
