I really don't know why you seem to find Chris' answer so impenetrable. Microsoft have abandoned their Windows phone product. This happens all the time in business, not just software, e.g. you'd have difficulty trying to buy a brand new Volkswagen Beetle straight off the production line these days, even in Mexico.
Do yourself a huge favour and upgrade your handset to an Android device, something like a Samsumg Galaxy. Not only are they miles better than Windows phones; all your favourite apps will work, usually much better than they ever did on the Windows phone.
