Seriously!?

if you bought it on a card, then speak to your card company. it's well within 14 days.
 
you are under the assumption / entitled to updates , for at least a year... if they aren't supplying em.. I feel it's a breach of contract.. and if they didn't make you aware of the "no updates" pre-buying it or the fact there is no "future versions / development".. you have every right to demand your money back, they have neglected to tell you this.. and it's an important thing, when buying something.. much like something is "reduced to clear".. you knowingly know they aren't getting any new things in, so the price is discounted accordingly... it comes under "fitness for purpose" also.. you should expect bug fixes for a year, unless told otherwise.
