My system is Windows 7 x64 SP1, Intel Core i5, 8GB RAM

I tried the following without success:
Unninstall Quicktime
Deactivate DEP (Under BIOS and Windows)
Reinstall with admin account.
Updrade the RAM of video to 2048MB

The error occurs when I try "Open a Copy on Sound Forge" , then the application unexpectedly quits with the error above mentioned.

I need a solution urgently!
