Haven't used WMM for a long time and now when i'm trying to make a slideshow movie of pictures, things are not working correctly.
That preview player doesn't work. When i edit start or credit text, player is just blank, i can't play the show or even save the movie to hard drive. I got 2.1 version.
Have you used any aggressive registry cleaners that could have damaged it? Reinstalling it "may" fix it, I don't know if you can download WMM from Microsoft or not as searching Microsoft Downloads didn't turn up any WMM setup file for XP.
I'm very frustrated right now. All i need to do is a simple picture slideshow and i can't do that! I don't wanna download any fancy program for that, because it's possible to do with MM, only if the god damn program would work!!
I don't know if this clears anything, but i get "class is not registered" when i click 'play' on preview player.
Don't forget you can also very easily make slideshows in IrfanView either .SCR screensaver format, or .EXE. Just throwing you another viable option like DennisD already has since WWM isn't working.
