Mods don't work with the GB stock scenarios. To play these with mods you have to DL the SDK which includes the scenarios, then rename the ones you want to play as mods...plus, put them in mod form. Yeah, suks I know, but at present, that's the process.
Hopefully, down the line, this can be adjusted, possibly in the line of 'permitted' mods that don't allow cheating in order to earn those coveted General Stars and Bars.
