For some reason, this morning when I fired up the demo version (standalone), the keyboard didn't draw in the window. When I played the keys on my controller, it made sounds, but I had no way to change anything, because the window that contains the keyboard was just a big blank grey window.
I tried re-installing (by deleting everything that had the words "miniMg" and "arturia" in it), restarting, even logging in as a new user, and nothing seems to help.
Any ideas?
