Uninstall problem Digidesign MBox 2 Driver in OSX 10.7.3.

[8Finch]

When it comes to recording, I'm still basically a beginner.
I just purchased a new Mac Book Pro which I want to do some simple demos with Garageband.
I went to the Digitech/Avid site and downloaded a driver which powered up and recognized my older MBox 2.
Then the problems began....
Garageband became either painfully slow or won't open at all.
I had error messages that "detected a midi timeout", "midi settings not available" "Selected Driver not found -10202" and of course the MBox won't work!
Apple says this needs to be straightened out on Digidesign/Avid's end, as I have completely uninstalled and reinstalled Garageband.
I have a feeling any driver uninstall I have done is incomplete.
Any ideas what's wrong?
I hope this is enough information so one of you experts can help me out!
