I purchased Photoshop Elements and Premiere package today.  I have been trying to download them but it tells me the serial numbers are inapplicable.  I am using a mac book pro and I have just noticed that the platform in my receipt says 'win" .  I don't remember being given an option for mac or windows  when purchasing.  what can i do now?
