I made an account and began playing and testing the game out excited to see how it stood currently. I alt+tabbed out to check something and had to use task manager to shut the game down completely because of this. I'm basically used to this on just about every game that exists even if its annoying.
I started the game back up and it takes me to the login screen again, I type my info and it says I've got the wrong email or password. I try to make a new one and it says its taken, I tried again but it wasn't working. Sad to say but I'm requesting a refund via Steam because that's just not something I'm going to fight especially when I have no emails from you folks stating that I successfully signed up but the second I make a forum account I get an email in seconds.
I wish you the best of luck and hope you can sort out login issues one day.
Sorry that happened to you. Maybe @a_lomo or @lindseyhandley could help you out. I remember when I signed up that I didn't get an email for it, so maybe it applies for everybody and support for changing the password without contacting the devs will come one day.
