Hello everyone. I'm very sorry to report that MyTube has been experiencing significant troubles lately due to various changes at YouTube, and currently provides no functionality at all.
I can assure you that a 2.0 version is, and has been for quite some time, in progress. However, while I'd love to have it up and running again soon I can't currently make any promises on a timeframe, as such an update will require substantial rewriting. Please accept my sincere apology.
Thanks so much to all of you who have supported the widget in the past. I hope to bring you another version at some point in the future.
