Hi Bill,
Please try the following things and let me know what you find:
1. Get the old mdb files (the one you used before the upgrade)
2. Copy them into other location
3. Add them/register them using Options dialog
Does this solve the issue?
Also, when the DCM doesn't pop up, do you see any message in command prompt window? If you do, what is that?
Thanks,
Sam
