Movie maker Youtube upload issue

I have multiple youtube channels I manage but only 1 that I upload to (not my primary)   I cannot find a setting in Movie maker to allow me to specify which channel to send the content, it used to work but now its uploading incorrectly and resulting in this program making what should be a simple process take three times as long.  Is there a way to set it to go to a specific channel and if so how?  I've tried setting a seperate 'password' through the 3rd party settings on youtube that was suggested elsewhere but Moviemaker refuses to recognize that information to allow an upload
