Have you tried uninstalling and re-installing the software. Perhaps there is an updated driver for your system since you first installed it, or maybe yours is simply corrupted.

Try these steps:

6. To exit TECH MODE, press MENU # 1 9 3 4 in rapid succession, as if you were dialing a phone number. The operator panel should no longer display TECH.
