Inserting Livjournal layout, having issues Options

[Tomates]

Ive had livejournal consisted in my life for a few years
though i took a break and recently made a new account and started to post more.
Though ive noticed lots have changed since.

Im having issues trying to put in a layout.
Im using the s2 version and i have a plus account

and usually i do
Journal > customizze journal theme
and i go to the part where it says Custom CSS and i will enter the code and they layout wont show up
it either just doesnt show up completely or its completly disorted and only the background pattern will show.

I know this is really stupid but its driving me absolutly bonkers!
I was trying to use a layout from Premade_ljs and i did go to the questions/faq's but they didnt seem to "fit"
like the certain things dont show up on mine.

I would love help
