Plugin audio problem

I was curious if there is any bugs with the plugin trials. I tried to try out the omega granophyre plugin today before work and it just gave Me problems with unwanted noise. I checked all My drivers and set it up as I normally do with My two-notes torpedo captor x but it wouldn’t cooperate. I had a similar issue with ezdrummer 2 until I bought the full program and everything setup proper after buying that software. Have people experienced the same with these neural dsp plugins?
