If the servers are down you will not be able to play the beta. When the game hits retail you can play without connecting to them.

I am able to connect to the servers now and play so they appear to be up.

I just got the same problem after reading this. It must be the update to Contagion. 

The same.

Thanks for the heads up, sean.

I get the same thing with Steam:

"Login failed.  You may have missing or stale registry data.  Try running Fallen Enchantress with the command line parameters /username "myusername" and /password "mypassword" (replacing the values in quotes with your actual username and password)."

Voztron, I tried that but it still doesn't seem to work.  can you show me what it looks like in the target path line?

Issue resolved! 

I think sometimes you need to start the game up a few times before you can log in currently.

I haven't made any changes and I still can't login so maybe it's on and off. I tried 3 times.

Is there any status on when the servers might be up?

Well some folks seem to be able to log in and others unable to.  I put "C:\gamepath.ext" /username "myusername" /password "mypassword" but still says I have login failure.

Just another reason I will never purchase a game that requires me to be logged into the internet to play. I will be glad when beta is over and I won't have to connect to play.
