PHP error & scores not saving

Hey guys, using the latest ibProArcade version with vBulletin 4.2.0 PL2 and getting a couple problems. Looks like this PHP error at the top of the Arcade when loading:

PHP Code:

Warning: stristr() [function.stristr]: needle is not a string or an integer in [path]/arcade.php on line 5550 

Scores are also not submitting correctly. When submitting any score, I am simply redirected to forum.php. Any help?

the link in my sig will bring you to the fixes .. in there youll find a arcade.php with the fix for this
upload it over writing your current root arcade.php file

Thanks Hippy, your arcade.php file and index.php edit worked like a charm.
