Dashboard 2.0.3 vs. MacDrive

Dashboard 2.0.3 has been buggy as hell for me since I updated from 1.8; it’d occasionally not be able to detect my FS, but still kinda worked most of the time (constant problems with auto-update and DroboCopy aside…).
I just had to install a copy of MacDrive in order to pull some files off of a client’s external drive, and now the Dashboard is permanently 'effed. I’ve uninstalled and re-installed a couple of times, wiped any Drobo-related files off of my program drive, but nothing seems to work; it refuses to detect my FS.
It seems like there might be a conflict w/ MacDrive… Any ideas as to what part(s) of the Drobo connection might be conflicting with the MacDrive install…?
