I entered my passwort in the impulse launcher. The first time I mad an error, but already when I tried for the SECOND time it said. "Max Login attempts reached. Please try again in a FEW HOURS".

Then I tried to retrieve / change my password. I got an email, followed the link, and changed my passwort. First it confirmed the passwort link, but then it said something about "system hickup". Now I cant log in with either passwort, and changing it wont make a difference.

Thats not how you treat a paying customer. If I had pirated the game I could play it right now.
