I apologize if this is the wrong forum to post this on.

OK I'm about to have a stroke, this is the second time I have done this video from scratch. And every time I try to save the movie file I get an error that says something like this:

WMM can not save the movie, make sure the original files used for the movie are still available  (they are I made sure the second time not to delete remove or move anything)  that the saving location is available (yes I have tried different places)  and that there is enough space to save the file yes over 70 gbs left. 

As additional info my C drive is in NTFS format not FAT 32 so file size over 4gbs shouldn't be a problem.

Any suggestion will really be appreciated

Thanks in advance
Dan
