Version: 2008 Operating System: Mac OS X 10.5 (Leopard) Processor: Intel Email Client: pop I've received .wmv files before and was able to play and send them. I could also come back later and retrieve the attachment from a previous sent email, play it and resent it but now, I get an error; 'unknown error in Entourage'. The attachment is there but always that message when I attempt to open the file. Inside the e-mail itself, a red X is placed.
