"Send to YouTube" fails.

YouTube detected my video as a duplicate when clearly, there was a big difference in between an old video with errors and an improved/fixed one.

I know it's my fault that I forgot to delete the old video but can't that be dealt with by MuseScore as well? YouTube has ruined a lot of peoples' upload schedule and I'm fucking sick of it encountering all those rare bugs.
If I decided to make a video and edit, it'll take hours due to laggy PC and slow internet connection (only at about 200kbs).
