speedline mpm UP-100

I have a UP-100 screen printer that was locking up on me by removing my cursor and not allowing any button presses. I did a hard reset and this fixed it temporarily i now have encountered a new problem where the unit displays a "communication error""Press any key below to continue" i do not currently have a support package and wanted to troubleshoot this myself if possible any hints that will lead me in the right direction would be much appreciated.
