Hi all. I've followed the directions from the flatclone readme (I thought I got everything). However, after I upload the flat.php files (renamed as flat2.php), and reload my shipping module, I receive this error:

Fatal error: Cannot redeclare class flat in /cart/includes/modules/shipping/flat2.php on line 23

I tried changing "class flat2 {", but that didn't work either.

This is incredibly frustrating. I don't understand why the shipping module would NOT have different shipping methods available by default!
Has anyone else had the error above? I would really appreciate getting this working.
