WDVD Maker

I am having problems using WDVD. If I try to save to DVD from WMM the
program opens up and loads the file but when I click on next a message comes
up saying that DVD Maker has stopped working check for solution on line then
close program. I do this nothing happens. Now if I open the DVD program and
click add items the program freezes and I have to go to the start button and
restart the computer for it to close. Any advice would be very much
appreciated.
