Windows movie maker issues

I’m trying to create a movie with movie maker, but when I try to save it I get a message about virtual memory. I don’t recall the exact message, but it states that the virtual memory is being increased because it was low. Current setting for virtual are 180 min – 360 max. I can save the layout, reboot, bring the layout back up and try to save as a movie, but I get the same message.

I’m also getting a message saying that the movie can’t be saved because “souce files may have moved, lack of disk space or insufficent privliges. I know its not privliges, because I can create a small movie and save no problem.

Any thoughts or Ideas? I’m in a jam because I need the movie for a wedding Saturday (2 days).

The system is a P4(celeron) 2.0G, 128meg and 20g hd.

Thanks
Tim
