It says" verify that the original source files used in your movie are still available, that the saving location is still available, and that there is enough free disk space available".

Yes, I have it saved as a project first
No, i didn't change any of the source file names
Yes, I have enough disk space, (I have 16 Gigs free and it's a 23 meg file.)
Yes, I've tried saving in smaller size

So what's the problem and how can I save it or convert it to a normal mpeg either making windows movie maker work, or using some free coverter, and yes it has to be free because I'm 17 and i have no money no credit card and a cheap dad who doesnt even buy me clothes, but on the same hand wont let me move out till the day im 18.
not the point
point is
help?
in reply to the first responce: that is exactly what it's NOT letting me do, that is when the message comes up

You did save the file project, but did you go File and select Save To Movie File, it would save it as a WMA/WMV file.
