@JaBBawockee - I wonder if it's running into an error and just not displaying it properly. Any chance you can make a ticket regarding the same subject but also send in your logs with it? Preferably after freshly recreating the problem where you're trying to upload to Youtube.
To send logs you just right-click on the Plays.tv taskbar icon, select Help > Feedback, fill out the info and make sure the checkbox is selected. Post back here to let me know you have sent it.
DID THIS GET SOLVED, I HAVE THE SAME PROBLEM
It should be resolved as of version 1.15 of the client. You may need to download it from the website to get that version.
