I think that you might have missed adding your extra fields in the code modification to easypopulate.php in one or more places. The error is telling you that the columns you are trying to import don't match up with the number of columns the script is expecting. Or possibly the order was added incorrectly in every place you modified. If you followed my tutorial in this forum there are 7 places to insert your extra fields in easypopulate.php and they all have to be in the same order and without any typos.
I suggest re-checking your modifications to make sure there are no errors.
