A common issue we are getting is people are creating an account and not registering their key given. This causes no servers to be listed when you login to the game. If you are having this issue please follow these steps.

• Register for an account at https://www.heroenginegames.com/therepopulation.
  
• Right click The Repopulation in your steam library, choose View CD Key. Click Copy Key to Clipboard
  
• On the website listed above click on your name if you are logged in and choose redeem key and paste it there. You should also see a section called Have a Key, you can enter it there before or after creating an account
  
• Have fun playing :-)
  

We have other solutions sticked in the Forums as well for some common issues that are cropping up.
