Hello,
I also have the exact same problem ; Retrologue 2 hangs or crashes after about 5 Preset changes on my system. Once it has crashed it will not load in my DAWs anymore ; I can get it to load again if I re-install it and restart the computer, and if I am lucky. My plugin scanners return error messages.
R2 always had that problem on my side, except right after a fresh install of Windows, something (maybe OS updates) seems to break it here.
I am wondering if any of you was able to find the cause of this since these messages were posted.
Thanks
