Warning: Missing argument 20 for skin_Arcade

I just installed the arcade on a clients' site.
When we click on the arcade link, or go to /arcade.php, the follow warning appears at the top of the arcade page -

Warning: Missing argument 20 for skin_Arcade::start(), called in [path]/arcade.php on line 1953 and defined in [path]/arcade/skins/skin_Arcade.php on line 220

Any help is appreciated.

Anyone? MrZeropage??

yes, I am here

I think the files are not all up-to-date, please re-upload both /arcade.php and /arcade/skins/skin_Arcade.php and make sure to overwrite them
