mailout mac projector

[louise yellowlees]

please help.
I have been doing email flash flyers and have created a mac and pc projector through the publish button, i have set the publish setting to publish both mac and pc.
however when it comes to sending the projector through email the pc one works fine but the mac one wont open. The flyers are created on a mac, and having sent it from the same computer to back to it, it doesnt recognise what it was written in and doesnt give you the option to open it in flash. why why why....does anyone have any idea and has anyone else had a similar problem?
please help
