Problem linking to arcade

[Adamant101]

The arcade on my forum is located at www.warriorsrpg.com/forum/arcade.php. I can access the arcade fine through the link on the control panel. However, whenever I click on an actual game, it removes the "/forum/" part. For example, when I click on a game from the "Newest Games" table it goes to http://www.warriorsrpg.com/arcade.php?&act=Arcade&do=play&gameid=10 when it should be going to http://www.warriorsrpg.com/forum/arcade.php?&act=Arcade&do=play&gameid=10. Because of this, I always get a 404 error whenever I try to open up one of the games. It also removes the "/forum/" part whenever I click on one of the internal links like "Leaderboard" or "Your Rankings". It does go to the correct link, however, when I click any of the "Play Game" buttons in the Game Information table! If you go to the links I specified, you'll see what I mean...

Is there any way to fix this?
