Google Analytics has killed my blog

Hi,

I tried to install Google Analytics following this video (Getting Started with Google Analytics). I installed the code manually EXACTLY like it says in the video, but now my blog doesn’t even load? I can’t get to the admin pages. I’ve removed the Analytics code using an FTP client but still the same issue.

Is there anyway I can solve this?
