can't play planetary annihilation on steam!?

I opened the game and it told me to log into the Uber password and ID. I did so and it said that the title has not been activated. What is that supposed to mean? :cry:

It's mean there is some problem with automatic account linking.
You can manually link your Steam and UberEnt accounts here:
https://uberent.com/user/linksteam
After it's done you'll able to play PA though Steam or Uber launcher.

You also need to log out and login again on forum, so you get access to alpha subforum:

Thanks for your help, I can play PA now

when i have written my passwords and click sign in it just said
"Sorry, an error occurred while processing your request."
