Hi John,
tried your suggestions...
Compatability/Administrator and antivrus exclusions.

All loads faster as you said, but problem exists.

Running program from main hard drive.

Midi/Audio setup hasn't changed, same as setup in BIAB, but checked anyway. Problem exists.

Is there a way to install RB without having to go through the whole BIAB installation process?
If so, I would like to give that a try.

I may also, as a last resort, do a system restore to see if that helps.

Thanks for your suggestions anyway John.
