Freezes during "Loading: Content" On Splash Screen

Hello everyone,

I am running Snow Leopard on a Mac Pro 2x2.94ghz Quad Core computer with a Fireface 800 interface.

When I load Cubase 5, the program is freezing on the splash screen during the “Loading: Content” portion.

I have tried to delete preference, and rename the plist file to “old.” The program works every time I restart my computer and open it, but after it is opened, closed, and then reopened, it will freeze on the splash screen during the Loading: Content portion, as aforementioned.

Also, I have noticed that my presets I make for channels will disappear if I ever have to Force Quit Cubase.

I would greatly appreciate any advice you fine folks could offer.

Thanks for the help.
