Capitalism 2 and Capitalism Lab Forum

I get the following error message when I log in. Just to ensure nothing is wrong from my end, I downloaded latest release version 4.4.20. I've attached a screenshot of the error popup, and until it is corrected I'm prevented from starting new games.

I've just noticed this situation for the first time this morning, Monday May 29. I started a new game on Saturday May 27 without issue.
