After the last update I get a message about the savegame being corrupted. It blocks the main screen buttons and it won't allow me to start a new game. I can't do anything else and I have to alt-tab and quit the game manually. When I restart it the problem recurrs.
I tried to look for the save game in the game folder, documents folder and subfolders, and the unders folder but I could not identify it so I can't erase the offending file. An option to delete the save game or to restart with a fresh savegame would alleviate the problem.
