vvvvid modified script

[Danielix99]

Hi i were just using your script that seems to work nowadays, but after searching into my window object i found that vvvvid created a new cab property called cab5 instead of cab4, and they modified the startadv function to include their new politics about ads using premium, at the moment your script still work but for cab function theres no need to change any lines of code; instead for the startadv function maybe would be better if you check it out;
