I tried exiting the Gateway application, then reopening it, but it still has the "Download" button next to Dragon Saga.
I also tried restarting my computer. D:
Greetings,
It sounds like your Gateway didn't patch completely or properly. Try reinstalling the Gateway and then try running the game client again.
If you have any other issues, feel free to let us know!
