Arturia FX Collection VST's don't run in WL

Hello there,

I just bougt the Arturia FX Collection VST bundle. Strangely the VST’s don’t run in WaveLab (tried WL Pro 10 and WL Pro 9.5). As soon as I want to start the plugin WaveLab gives an error and the VST does not start. I can continue working in WL though, where the error says I should restart WaveLab.

In Cubase Pro (11) the plugins just work as I expected.

Why do these VST’s not work in WaveLab Pro, but do work in Cubase Pro?

WaveLab often exercises less used parts of the VST interface that are neglected by some plugin manufacturers. In these cases it is worth verifying with them whether they test with WaveLab.
