Thanks Curlycord. I will contact them next.

This should be as easy as turn down the system, replace the NT5B77AA and restart, correct? Upon startup will the new VM will tell the KSU about the codes or do I need to wake it up first? While I do not look forward to reprogramming it, I am proud of myself for documenting their scripts and trees 5 yrs ago. I always leave a copy with the client but even with having 3 of my work laptops stolen, I miraculously still have word documents on backups. I'm usually not that lucky.
