I changed it, now I can't find it to chage it again! CRAZY

First of all, site in question

http://www.precisiononeammunition.com

If you view source, of course, you see your meta tags....title, description, keywords...etc. I filled in the info when I first made the site and I wanna clean it up now. I can't find the raw file with the meta tags.

I know there are 100000 threads that tell you where to find them at but those, aparantly are not the ones I changed it in.
These are the ones I keep reading about that are not the correct ones.
includes/languages/english/meta_tags.php
includes/languages/english/YOUR_TEMPLATE_NAME/meta_tags.php
blah blah blah. someone help me. My eyes hurt

Have you tried using

admin --> Tools --> Developers Toolkit

Then scroll to the bottom and enter one of your meta terms in the Search box under where it says,

Look-up in all files
Key or Name:

that should find the correct file.
