Blue8817, are you using Nero Home? It is a media center, something like the Windows Media Center built into Vista Home Premium and Ultimate. I suggest that you disable Nero Scout and Nero Home. I prefer to have Nero only run when I ask it to, but like so many programs it wants to install background tasks and services that you don't need.
* Go to Start -> All Programs -> Nero -> Nero Toolkit -> Nero Scout. Uncheck the box "Enable Nero Scout"
* In a Run box (Win+R), enter "serivces.msc". In Services, stop the service NMIndexingService and disable it.
By the way, what is the application name that has "stopped working" in that error message?
