Big problem with WMM 2.6.  My son has this downloaded on Samsung laptop with Windows 8.  He has a long movie--over an hour--he's been editing it on MM 2.6 and is not yet through.  He would like to move the movie to another computer and is trying to find a way to copy the movie to do so.  He just tried saving the movie on his computer and the error said it couldn't save it "windows movie maker cannot save the movie to the specified location. 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, and then try again."

He is panicking as he can no longer save it or move the file to another computer (mswmm file will not copy to a flashdrive and is not convertible on any free formating program that we know of).  Any help appreciated!
