Error in my vBulletin

[ano2k77]

Right, so quick rundown

My disk failed 2 nights ago on my server which I host my forum on, I have the backup of the database which is all good, but my files (in public_html) have gone forever

I re-downloaded vB 3.8.9 and added it to my new server, I've installed it to my current database, at first I had errors regarding dbtech > usertag etc (which I've added in and fixed)

Now I'm getting this error all over the place:

PHP Warning: include_once(..../mobiquo/smartbanner.php): failed to open stream: No such file or directory in ..../global.php(1091) : eval()'d code on line 112

What does this mean? I don't recall having any folder called mobiquo on my old site? Is this a modification or to do with my forum skins?

Also when I try and login, I get this:

Unable to add cookies, header already sent.
File: /home2/habhitsfor/public_html/includes/class_core.php
