Vista - Windows Movie Maker problem

I have recently been working on a movie for my friends wedding. Everything has been working fine up until recently when I have began having problems with the photos and music matching up. The problem is quite strange. If I click on a particular photo at random the music matches up just fine, but if I start the movie from the beginning it no longer does. It is a very strange problem, but now everytime I have to edit something I have to do it by starting from the beginning of the movie to see if it editings correct, as you could imagine its getting quite annoying. Didnt know if anyone else has run into this problem; any advice would be greatly appreciated.

I am trying to use my Windows Movie Maker and it keeps telling me that "Another User is using this program on this computer. Please close the other session of windows movie maker before starting back windows movie maker."

Can some body please help with this problem. I would like to know how to fix this problem step by step please.

I would be very grateful if somebody could help me.

thank u.

I just found out how to fix the problem I wrote on.

To allow pictures and music to be able to burn on anything u must bring down the quality of the file or video u are making.

After Clicking on Publish to/Burn,
Give your file/video a name and choose where u want your information to be saved,
Then click next,
Click the down arrow at MORE SETTINGS,
Choose WINDOWS MEDIA LOW BANDWIDTH(117 kbps),
Click Publish/Burn and it should save to whatever u choose it to save to.

Hope I was helpful to anybody that experienced the problem I faced.
