Pi Sound Radix doesn't work properly

Hi

I 've tested the trial from sound radix Pi and Auto Align 2 because I m looking for a Phase Aligment Plugin. The Auto Align 2 works but isn't suitable for me. Pi would probably the right one as I saw some YOUTUBE tutorial. Problem is Pi kinda doesn't work in FL Studio. If you put the VST3 on a Channel the sound is gone like muted. If you put the VST2 it seems kinda to work with sound but the GUI the graphs etc are buggy. And I don't really know if it is working or not. Somebody has a solution to that? Thx
