When I try to update I get a message "failed to extract project file to memory" and 'Failed to load update data file."

After I select the scenario, side to play and level, when I click to play the game window vanishes and I'm back to the small start up Panzers window.

Also my Africa Corps vanished and I cannot find it. How do I redownload it?

Thanks

Mike

Game quits after selections in Windows 8

Also my purchase of Africa Corps has disappeared. How do I get it back?
