Parse Error

Oh heck. I was just trying to comment out a few HTML tags in the kses.php file, so I didn’t back it up, and now I’m getting:
Parse error: parse error, unexpected ';', expecting ')' in /home/wrongnum/public_html/main/wp-includes/kses.php on line 45
And I can’t figure out how to fix it. I never touched line 45, so I don’t know what the deal is there. Plus, I’ve removed the comments from all the lines that I revised, but still it won’t work.
Any help here is appreciated.
