I deleted the game (folders under c:\users\user\AppData\LocalLow\KBSW also) and installed it again. Got the scenario and tried to load it under New Game. I got an error:
Error
Invalid DB Key:
WW2W_Intermediate_WW2_Enhanced_Set
What gives? Also I do recall installing scenarios from you before, but game gave me error for those too. Used to work before... Deleted them along with the game.
