You mentioned that you activated DBpro, but did you activate EZrotate?
Run TGCCertificateViewerKEEPACTIVE.exe again. Click the activate/register button. On the next screen, click the "Enter Order Key" button. On the next screen, enter your e-mail address (the one that is used with your TGC account) and your order key for EZrotate. You can get your order key from your "My Products" page in your TGC account. Near the top of the page there is a link that says, "Activation keys". After you enter your key, click the next button. EZrotate should then activate and all the commands should work.
I hope this helps!
