Sorry it tooks so long... but, I have a Mbox2 mini, Protools 7.4, and a some more plug-ins.
What I would do is TOTALLY uninstall all of the digi hardware and software and start over from the top... But I'm not THAT into protools so this may be the wrong way to go... I'm sure Marcus (themidiroom) could help you... He's a PT GENIUS!!!!!!! lol
