The problem is that the DLCs aren't available ingame. An error message appears when I launch the game:
Failed to load file "pmc|addons|air_pmc.pbo" - decryption of headers failed.
The game launches anyway. But I have no PMC or BAF new maps, missions and campaigns.
If I go to the "Expansion" option in the main menu, both BAF and PMC are installed and enabled.
My guess is that error is related to this problem.
Is there a fix for this, please?
