"Today Curse and GOG.com announced a new partnership which gives all Curse Premium Members their choice of one of GOG's most popular titles - FREE! This offer applies to all current Premium members and all new Premium subscriptions purchased between now and December 31, 2014. "

I wonder whether GOG knows that Curse is not fulfilling their part of the partnership, incriminating GOG and undermining GOG's public image with lies about "expiration issues".
I'm pretty sure GOG would never do such a thing as making the keys "expire" prematurely. But some people may now get such an idea!
