I bet they are still working in Dimension or Rapture too ...
As per my previous post @Mungus ... It's likely that it can't find the necessary MultiSamples/Waveshapes.
Reinstall (rather than download) may pickup or allow you to define the new MultiSamples directory ... but you'll likely be left with 2 copies in 2 locations on disk(s). You may or may not be OK with this.
I haven't installed Platinum/Cambridge yet so can't be specific with regard to the Gold Tops.
Other than looking in the registry, probably the easiest way to find your old Dimension and Rapture MultiSample/WaveShape directories is to right-click in that space on the old synth GUIs as if you were going to load a new one. (not the prog - the waveshape/sample).
You can then either copy or link the pack subdirectory to your RapturePro Multisamples directory (link example as above).
Also in RapPro - you can check the file (sample/shape) it's after by examining the active elements via the mixer and the element numbers at the top.
