This is going to bug me... it should just work. Do you have another computer to try it on?
Giving Process Monitor a chance may not hurt either. But I really don't know what we'd be looking for... other than some errors, permission issues, etc.
Oh, I know. I'd like you to download SQLCon32 from here:

This utility test conductivities - no CR involved at all. If this can not connect / retrieve data, then it is not a CR issue. IF it does work, we'll have take a closer look.
It's a relatively simple utility to run, but this doc explains it in more detail - if need be.
