Ran into a major problem with my install (installed 1.2.5.c on 1.5), it's not receiving tracking and my website won't load now. I get a blank page, favicon and title load, but nothing else. WTF

I have to agree though, I've never had a problem installing any modules and the writeup on this could be a lot better.

I uploaded all the correct files, renamed all the directories to match my admin and template. CHECK. At the bottom of tpl_main_page, before the closing body tag, I added the code. CHECK. Ran the SQL Install code, no errors, said everything went fine. I see the option now in my config. This is where I get confused though-what is this mention about a 'ga.js' file? This is directly after the SQL step. I looked and I don't even have that file in question and the only file in my checkout success folder is a header file, so what is this about?

So I pretty much did everything correctly and now my site is down. What do i do???
