directory problem! please HELP!

hello guys, I just installed this gaming software.

but for some reason the software is installed in the wrong directory of my site.

when I click on tournaments, your settings, your favorites, leaderboard etc...

i get an error page with the wrong dirctory address on the url bar like this

"http://www.xxxxxxx.com/vbulletin/upload/arcade.php?&act=Arcade&module=settings"

but when i manually delete the "vbulletin/upload/" from the adress bar and enter it like this;

"http://www.xxxxxxx.com/arcade.php?&act=Arcade&module=settings"

everything is fine.

how do I set the directory to the right adress for this software?

plz help

note= I had this same problem when i tried to install vbgoogle me for my forum too

please don't open double-threads here

maybe you uploaded the complete /upload folder from the archive to your forum ?
/arcade.php should be in your forum's root!
