I recently downloaded Cakewalk by Bandlab and tried to bring in my Cakewalk Sound Center VST from my copy of MC6 Touch. The program does recognize and load CSC...but all of the instruments that came with it are now gone, despite the fact that the audio samples for said instruments were also in the folder.
This also happened when I tried to bring over some of my other VST instruments.
Any suggestions?

It reads as if CSC was copied from another machine. There are registry entries created when CSC is installed. Without these entries the plug-in will not work. I am not very familiar with MC6T. There may be an advanced install option a couple of screens into the install process. If so, selecting it will display a pick list of components to install. This is the best way to perform a partial install.
