bought a copy of the Photoshop elements from the app store, installed first time on my Imac. i want to use on my MacBook Air, but it asks for a serial number/ 6 figure verification code. I have rung apple no help what so ever. I have spoke to Adobe no help at all. all i want to do is have it on my lap top to use in the field. This has been going on for 10 days now and still can't get anyone to recognise the problem, or better still solve the problem.
