Video Tutorials Plugin - Activation Failing

I posted this issue yesterday, but I can no longer get a follow-up on the thread despite my repeated posts. So I'm hoping that by re-posting it will trigger someone to look into this for me.

---Original Post ---
I attempted to activate the Video Tutorials plugin, but it says the site is "already registered by you or another user - please contact support".

Yet, when I attempt to use the video tutorials it says "Access denied"....

Please let me know how to resolve this issue.

I have already authorized support to access the site per instructions.
