Yeah I think the main game is done, I think a second one is going to be put in the works instead. Doesn't say to be continued at the end, only says "The End" whilst left on a cliff-hanger.
I'm getting the same thing and I tried both these options. It might just take awhile and OP didn't know. The download link from my emails says 404 not found, so probs doesn't get established until the purchase has fully had time to settle.
