I get the log in box on the top left of the game screen, but I don't get the log-in pop up. The game was working fine a couple of hours ago, and nothing has changed on my computer, so I'm a bit confuddled.
Having the same problem here. clicking on "login" in the top left corner of the gemcraft window only brings up the Armorgames login window for a fraction of a second (too fast to read anything - I just see a white flash) then it's gone. Cannot login to Gemcraft Premium as a result.
Problem affects both of the browers I tried (Firefox and IE).
I've talked with uspatriotsf through email a bit to try and solve this issue with no luck unfortunately.
