I downloaded a kit that says I could open it up on Adobe photoshop or illustrator. I have both of the latest versions and every time I try to open this file on either program it says that it couldn't complete my request because it's not the right 'kind' of document. P.S. I'm trying to open the Submission Kit from Threadless. is the site's download defective or could I change the download to a different document setting? and...how would I do that?
