Here is a neat trick for you. Load up the 1066 scenario, save it straight away, then quit the game. Open up the 1066 eug file and have a look (just so you know what you are looking for), then go into the saved game and copy the information into the eug file from the saved game. Save the eug file and restart CK, everything should look ok. Please note you cannot save the eug file if CK is running.
