MM32 Won't Reset or Stop Sequence

Hello.

Don’t know much about this synth other than the greatness it pumps out from watching YT vids. Decided to purchase one second-hand on eBay. Just opened it, fiddled around with it attempting to learn how to create a pattern, but now it seems that it won’t shut off the pattern via the Run/Stop button, or Reset it. Not sure if I was pushing too many buttons or what.

Anyone else had these kind of issues?
