Uninstall your norton 360

[BenRatt]

If your having problems with your typewriter locking up uninstall norton. I must have been sleeping in class the day Daniel told us never to even think about adding any software to the control. I had three or four techs trying to diagnose this problem for me over 6 months. I replaced the serial card, PLC, air press regulator, check valve, motherboard, and serial cable to no avail. Finally talked to Kevin one day and he suggested uninstalling any AV software. Problem solved. Somebody buy that man a coca-cola

Well Ben look on the bright side. You have a few spare parts if something goes wrong.
Maybe Kevin needs a 6 pack of something?
