Unsurprising. I tried rather hard to get NUGEN to look at all my WaveLab crash reports related to their plugins and they did not seem interested in trying to solve the issue.
I like their plugins but I had to omit them from my workflow in WaveLab and haven’t looked back since. or even felt the urge to re-test them to see if they got better which is sounds like for the most part, they have not.
The fix lies with NUGEN.
