I bought a sound pak (Hammond B3 Organ) from the Cakewalk store and installed it. It shows up in Dimension Pro, but whenever I click on one of the presets, I get a small dialog window with this in the menu bar area: IDS_MULTISAMPLE_NOT_FOUND not found in text resource....
 
Inside the dialog is this cryptic message: org-5-1#3'FstSFb.sfz
 
I read some old posts on this. Am I looking at the ol' uninstall, re-install, mess-with-the-registry issue, and make-sure-I-back-everything-up scenario on this?

It's a terribly done install package. I bought it as well and it was the stupidest install I've ever done for a VST. You figure a Calkwalk product installed on a Cakewalk only computer would find the correct folders automatically,,, nope. 
It was something to do with paying attention to where the unzipped folder was going. I think it goes to some temp folder in nether land if you don't change the path. It's supposed to go in Rapture? Anyhow I had to find the multisamples and the dll. and manually move them to the Dim Pro ?? folder. It works once you get them in the correct place.
