I get that too, always from the historical accuracy screen... If you go to task manager and exit the program you will start at your last save. I have mine set to save Jan 1st of every year, so I have made it a habit not to look at historical accuracy screen until after the Jan. 1st save.

Edit - Other than that error message once you shutdown and reboot I won't get that error again until I open the historical accuracy tab again .. sometimes it works fine and sometimes it doesn't... kind of a mess!
