A couple of month ago i purchased a new Sunnto sports trainer(watch) i have been running XP for years but the Suunto software was not compatable with XP so hadto find another option, thought about getting a newer Mac but as i had a Dell 960 with 4Gig of ram i went for Windows 7 Proffesional from a seller on ebay, the packaging looked ok in the listing and it appeared genuine when it arrived, got it all up and running but after a day or two i got the message that Microsoft thinks you have invalid software. It gave a phone number to ring to validate and i did so and it all appears fine.
was 12 squids.
