I need help

I loved this skin right from the moment i saw it the first time so I installed it (including the "options" addon and the "auto detection". both work just fine btw) but the style overrode my 2 original styles. (atleast i looks like it did)
this is how it looked before:
and this is how it looks now:

i've read that vbadvaned causes problems so i disabled it but it didn't help at all...
also the page doesn't reload after changing the skin with the quick chooser

i would be pritty upset if i had to do a rollback on my server (i already uninstalled the skin but the result was the same. my styles are messed up)
i'm running vb 4.0.7 with the following addons installed:
Admin Log In As User 3.21
Footer Link 1
LAM - Quote Img to URL 4.0.6
Lightweight Style Options 1.0.0
Mobile Device Detection 1.0.1

Tabs en vBulletin 4.x 2.0.3
vBadvanced CMPS 4.0.1
vBSEO 3.5.2

can someone pls help me out and tell me what i did wrong (i installed it as i was told in the instructions in the first post)
