I tried downloading the FCB Manager for my Windows PC and at first it worked (mobile version). When I tried to map my MIDI options, I made a mistake and the application wouldn't open without hanging. I ended up uninstalling completely. Now, after re-installing, the FCB1010 Manager app wont open at all!
I've downloaded the latest JAVA, ensured MIDI USB connections are correct, ran as administrator, reset my FCB controller, all of it.
