I recently noticed that I have multisamples for Rapture, Dim Pro and CSC in multiple locations. Just searching for one of the flac files returned 4 versions. I even found a multisamples folder in the dimension pro/multisamples folder. Has anyone else run into this? If so, how did you remedy it. Is it possible to delete them all and do a fresh reinstall?

Yes, i am dealing with this. I am consolidating everything in Rapture Session.

Deleting and reinstalling is always a last resort for me. I just made sure I had a backup of everything and copied the multisamples to C:\Cakewalk Content\Cakewalk Sample Data\Rapture Pro\Multisamples and the related programs (presets) to C:\Cakewalk Content\Rapture Pro\Programs.
