The servers crashed. its been like this for about a day now. If you go to the TLOPO website it says that they're investigating it. No word yet on anything else.

You have to go re-download the game. - They had a launcher update if you've not seen the official site. - However, you will have to wait till tomorrow when they re-open the servers. :)

Hope this helped!

I downloaded the installer again as directed and can now login and play pirates. Thank you all for your helpful feedback.
