link to arcade is wrong.. ?

[imhere2009]

Hi all

Ive hyst installed this arcade with the lastest versionof vbulletin, vbulletin i have in my main directory so when you goto www.rpg-talk.com it opens my forum, though when i click on the arcade and click on a game it akes me to a page using this link http://www.rpg-talk.com/forum/arcade.php?&act=Arcade&do=play&gameid=1

notice the /forum/ this shouldnt be here and if i remove it from the link it works, any ideas on how to change this so it would goto this link instead as it should be? http://www.rpg-talk.com/arcade.php?&act=Arcade&do=play&gameid=1

Any help would be great.

Thanks
steve
