I am having problems with Movie Maker when publishing to YouTube - it saves the video and says publishing. Gets to publishing 100%, finalises upload, then a dialogue box pops up with "Your movie was not published because there was a network problem."  Upon clicking the "more information" box it tells me "'XXX.mp4' failed to upload to with the following error: "Gone
No longer available".

Checked and double checked my Internet connection - no problem.  I can save movie to PC and it lets me upload mp4 files manually from Documents into YouTube.  Tried uninstalling and reinstalling Windows Essentials - problem persists. Help!!
