Just wanted to give a shout out to PG Music Tech support. We worked through this issue and Realband is now running. Although we aren't 100% sure, it appears that there was an issue in the Windows registry when DX plugins were being scanned. Tech support spent close to 5 hours helping to resolve this issue. I just can't say thanks enough! Even though I can't tell anyone exactly, I wanted to at least put out what we feel the issue was so that hopefully it will help someone else in the future, and give credit to Tech support for not giving up on a very frustrating issue. Thanks again!
