VST3 crashing Nuendo 5 (and 5.5)


when loading Nuendo, it stops working when getting to ‘initializing Nuendo Plug-In Set.vst3’

Soon as I rename the VST3-folder to something else, there’s no problem - except me really missing Reverence et al.

as I have both 5.0 and 5.5.3 installed and they both crash when initializing, the problem seems to be outside Nuendo. Anybody having a clue as to what can be wrong ?!
