SWF TC-601 Blank screen after overload error.

My Machine had been running fine. All the sudden it got stuck pretty hard in to the material. This happens from time to time and I ususally just back the wheel up by hand and restart the machine. This time I turned it off before it ever gave me a error message. When I turned it back on all the job and machine info was blank, only the icons show up. None of the buttons will do anything. I've restarted a dozen times with the same result. Is there some sort of manual reset on the cpu? I don't want to lose all the designs on there, but I'd rather have the machine work. Good thing this was a practice job!!

Here is a pic of the screen.
