i found a crack/patch for "Composite Studio Pro 2" - it is the same as used by "WipeStudio 1.2" .
load "HF-WSR.LHA" from "~Uploads/emu/VideoToaster/WipeStudio_v1.2/".
extract and place the files "reg" and "def1" into: "cstudio2/data/" - replacing the original files there
in the original "reg" file they mention WipeStudio - and i recalled a crack for this - so i just tried and it seems working
