IMPORTANT: Note that you must have the Sontius FX, Cakewalk DirectX effects, and TH2 Producer (for Platinum, TH2 SONAR for Artist and Professional) installed on your system for the amps to work properly. Various elements of those plug-ins are "borrowed" for use in the amps.
I checked those out and found that the Cakewalk DX was corrupt in my X1, X3 and Platinum versions. Adding some of the Cake DX to a track FX bin, including Amp Sim, crashed whichever version I was using. I reinstalled all three versions, with updates, and while the Cakewalk DX seems okay now, the CA-X Amps still don't work for me. I have reached 110% of my aggravation limit so I guess I'll stick to GR4 or TH2 for now.
