I can’t open FM9 Edit all of a sudden on my Mac. Yesterday it was working fine, today the app opens but it is black, no connection with the hardware, and the beach ball is hanging and I have to Force Quit to get rid of it (many times…). I Did all the usual things: turned FM9 off and on again .. deleted and reinstalled FM9-Edit… changed USB hub … changed USB cable .. all same result, it hangs, it is not happy 
If it’s not the software, or the cable, or the hub .. should I re-set the FM9 back to Factory settings?
Has this happened to anyone? I'd be so grateful for any ideas.

... and they added good quality USB cables and a G66 T-Shirt.
