Having problems with Windows DVD Maker

This morning, when suddenly Windows DVD Maker has stopped working on my computer. Each time I try to burn a DVD, I immediately get an error that reads:
"Runtime Error! Program: C:Program FilesMovie MakerDVD Maker.exe abnormal program termination"
Then the application closes. I would very much appreciate any suggestions on what to do to resolve this error.
Note: I run Windows Vista and have noticed the error with both a blank DVD+RW disk and a DVD+RW disk with a movie on it that I burned yesterday using this same program.
Thanks for any help.
