I was working on my machine this evening and it was fine. When I turned it back on again 10 minutes after using it the buttons weren't working.

It turns on, the lightbulb works, it can sew straight but I can't change the stitches or use any of the buttons.

Just passing by, since I don't work with Pfaff Creative. Still, maybe these tips might help you? According to suggestions in comments, you might try to replace the lightbulb.
