One of the major changes to come with PureGDK 2.0 is the brand new website. To prevent any unforeseen problems with the transition, I have decided not to attempt to merge the old website's database with the new one.
What this means is that all accounts at PureGDK.com have been deleted and you will have to create a new one. Also, a coupon for a free copy of PureGDK 2.0 will be sent to the e-mail associated with your old account. This coupon can be used towards a future purchase at a 100% discount (free).
I'll try to get those coupons sent out later today. I don't know how long it will take for those who purchased from TGC to receive a coupon as I don't have access to your account information; I'm sorry.
I'll be sending TGC an e-mail about this later today. Hopefully we'll have a solution for you within the next couple of days.
