I just fixed it by finding my old 1.22 dll and moving it to the VST folder and re-scanning. I shouldn't have had to do anything.
The installation routines for DimPro and Rapture or horrible. They should either fix them or retire the products. Z3TA+ seems to go much better.
Also, Cakewalk should give us the option to download ISO images of the DVDs so we can burn our own DVDs. That way if we have to reinstall, its a lot quicker plus it will give us a backup version.
