Bought this boxed Microsoft product from Amazon., Wont install properly and error message produced a contact which doesn't exist. I refuse to contact Misrosoft as I only have a cell phone and 0800 numbers are expensive and no doubt lengthy, in any case seller has responsibility to provide kit for purpose. Tried on another pc with same results. Unable to get my money back as box has obviously been opened. very unhappy bunny some £80 poorer. Morale, never but software from Amazon again - this is an on shelf package and should simply work. (ps memory, disc space a plenty and Vista - tried it on a landline network but same result as my dongle. Frustrated!
