AotR Thunder at Karelova

[Der Landser]

Hi Guys, I downloaded Thunder at Karelova from TFE4 and dropped it into my AotR install. When I start the scenario, I get a File Read Error - Error reading scenario file. The map displays after I dismiss the error message, but there aren't any units or symbols on the map, just a blank map. My AotR install is patched to 1.04 and it's bone stock with no mods applied. The only additions are some scenarios downloaded from TFE4.

Thanks in Advance.
