PS3 Theme Builder error|PS3 Themes|Forum|PS3 Themes

Every time I try to create a theme in PS3 Theme Builder, I get an error and I have no idea what's going on. This is the first theme I've tried to create. Any help is appreciated.

The error says:

Unhandled exceptions has occured in your application. If you click Continue, the applictaion will ignore this error and attempt to continue. If you click Quit, the applictaion will close immediately.

Access to the path 'C:\Program Files\ PS3 Theme
Builder\IconDefiniton.bak'is denied.

See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.
