45 Seconds of "Black" in Cablecast schedule

One of your techs came to Country Club Hills, IL (May 1st) to fix the problem of a 45 second black spot that shows after each program on our public access station. The black spot was gone when he left but it came back that same night. When I checked the

computer I got a run time error: Program:D\TRMS\ControlModules\SXHWcontrol.exe This application has requested the run time to terminate it in an unusal way. Contact support
