7-day trial over - need to continue playing

[AndyK]

Hi

When I started playing the 7-day trial I was told that I could continue playing just by starting a subscription without buying the game (See this thread), but I can't figure out how. When I click on the link to manage the (now closed) trial subscription, I'm told to buy the game and enter the code found in the case.

How do I start a new subscription without buying the game and then link it to the trial subscription account so that I can continue playing my old chars if that is at all possible?

Regards
Andreas
