Sudden Parse Error?

I keep getting this error, preventing my site from loading:

Parse error: parse error, unexpected '<' in /home/ace/public_html/skins/1/3c-body.php on line 46

I haven't changed the template. I was wondering if anyone else got it too, and how it should be fixed.

I checked that line of my template, and looked to make sure brackets occurred in pairs, but that's the limit of my source-warrior skills.

Seems okay to me.
