CPflight MCPel and Efis Quit working

I had just inserted a script to work with the overhead OC gauges, and when starting up my sim the MCPel and 2 Efis units were dead, no lights, no nothing. Up until then they were running greatI am also using Marty Bochanes Prosim737 as my software package. Has this happened to anyone else, and anyone have suggestions on how to fix the problem?
