Question about Outlook Express

Hello, I'm desperate for help with Live Movie Maker. I have a project file that is five minutes long, consisting of several clips. I have a Windows 7 if that makes any difference. The files are in .MOV format, but there are so many that it'd be tedious to convert them to a perhaps more friendly format, though if it comes down to it...I guess I may have to do that.

I'd prefer to accomplish this goal without having to convert any files: I need to save this video as an actual video, in the .WMV format. I've opened up the project file on WLMM, clicked "Save Video," and selected "For computer." I have tried this over 5 times today, restarting the computer in between two to see if this would fix the problem. The problem is, the video gets about 40 to 50% saved, and then an error code will appear. I've gotton error codes 0x87260103 and 0X87160139. They say that the video cannot be saved, I think due to particular clips and audio files in the video being unable to be saved. However I can play through the project file fine, although at times clips will suddenly go mute or go gray and have the yellow ! triangle shown.

I'm desperate to get this video saved to my computer, but I've yet to succeed at this. I've tried this with other projects in the past, and a couple days ago I had a project file with .MOV clips and it successfully saved (albeit not on the first try, and it wasn't as long of a video as this one). The project I'm attempting is exactly 5 minutes long. My question of all of this is, what can I do to save the project in .WMV? Will I need to convert these files, or is this a problem with the software itself? And are there any other ways to convert the project file to .WMV? Any and all help is greatly appreciated. Thank you in advance.

I cant get the music on movie maker to skip over the videos. I want the music on all the pictures with different songs just not playing on the videos, how can I do that? I've tried everything and can seem to get help. I tried the set point and end point, that didn't work out for me, I tried to turn the sound down and off on the video, that didst work either. I just cant seem to get it. I just don't want the music on all the videos, is that to much to ask? LOL
