How do I upload games to the arcade?

[LoF]

I've just installed the v3 Arcade mod to vbulletin 3.6.8.
How can I upload games?

I downloaded the games from the list in some thread here, but it doesn't work.
I entered to the AdminCP, then to v3 Arcade category => Game Tool.
There I can click "Start" to get games from the FTP folder: admincp/games or /games.
I uploaded the games to there, but it doesn't work too.

And another thing that I tried - I uploaded the file: "pacman.game.php" to "admincp", then I opened it, but it wrotes me:
Fatal error: Call to a member function query() on a non-object in /home/topgear/domains/topgear.co.il/public_html/tgcontrolpanel/pacman.game.php on line 31

WHAT WILL I DO?!
