I had the "No scores submitted error" and here's what I did. I'm running the new update and VBSeo:
Excluded "arcade.php" in VBSEO settings.
AdminCP > VB SEO > VBSEO Options > Exclude pages
I also removed all references to the arcade in the Re-write:
AdminCP > VB SEO > URL Rewrite Rules
The arcade is no longer Seach Engine Friendly, but at least its working.
Hopefully a better fix is coming soon. Let me know if doing this worked for you (be sure to save what you deleted).
Be sure to check any links to point them to:
www.yourserver.com/forum/arcade.php instead of the HTML page.
