Installed Easy Populate v1.2.5.5 and everything went well.

However, when I try to import my CSV, i get the following error at the top of the page:

Warning: array_flip() [function.array-flip]: The argument should be an array in /homepages/25/d264521618/htdocs/cart/admin/easypopulate.php on line 1222

Any clue?
