I bought two apps that are suppose to open and play a WMV file attachment in email. I have tried web email and the iPad email and neither app that I bought would play any WMV file. Any ideas?
Did you try tap-holding the links to the files in the Mail app. You should get a menu with an Open In option. Select the Open In to get a list of compatible apps. If you have more than one or two you may have to scroll. That isn't always obvious.
