[help] Problem with index.php in Arcade

I installed VBAdvanced at my site and changed the index.php from vbulletin to home.php and the cmps_index.php to index.php.

When my users play in the arcade at the end, instead of them going to save their score, they get taken back to the vbadvanced hack which is the home page.

I tried editing the arcade.php since i found two lines which called for the index.php and changed that index.php to home.php but still the problem persists.

I am not much of a coder of php so i dont know what to do next.

Anyone who can help?

PS. on a sidenote, does anyone know how I can independantly change the tree info for the root? example:

(look on this post on the top where it says:
vbulletin.org Forum > General Codings/Questions > Premium etc)

I want to change the link from the vbulletin.org forum (of that link in my site i mean) from www.mysite.com/index.php to www.mysite.com/home.php
