Upload to YouTube

I posted the following from the MuseScore forum through the 'Help' menu within the program, but was advised I should post here. I was unaware that the forums were independent. Anyway, here's a copy of the problem I posted.

Yesterday I deleted a score from my channel on YouTube. Today I tried to upload the revised score to YouTube and got an email from MuseScore that the upload was successful. However, when I went to YouTube I could not find it. When I accessed my account it said there were no videos in my channel. Since I am limited to one upload per day, I could not try again. Can one of the developers determine what happened? My name is Charles Bond and my MuseScore handle is 'chasbo'. The score it titled: "Crammin'". Thanks for looking into this. It's my only score on YouTube.
