Hello, I'm having some weird issues with Acid 9, no idea what's going on .

First, starting today, every time I open the program (as usual), for some reason my main Audio Device is Rewire Device (which I don't ever use).

And then the program started to act out after I open a Midi file,

at some point it just stucks and eventually I have no choice but to close it .

please help . this is some serious stuff.

thanks, oh and I'm using a Windows 10 latest 1909 build .
