I broke my catalog

I was looking through a lot of files to figure out where the English flag was called just to the left of the currency, in that bar.  I wanted to change that for a US flag.  I must have deleted something because now on my home page I don't have products.  I have the rest of that page though.  So how did I shoot myself in the foot?
Any help please.

Also I did just rename my us flag to en.png but I was looking for:

       
   
   
     
     
   
so I could chang this line:

Never mind... it's fixed.  Must have had some cache stored giving me a problem.  Logged out the re entered the store and everything was ok.  So your suggestion was right on.  Thanks
