Until ...
yesterday when I purchased the blackturn DLC. Unfortunately I bought this DLC through gamersgate.

I have two recommendations for solutions if I may. I was wondering if you could help me either one:
1) get the steam key for the Black Turn DLC (I will supply the "standalone" dlc key I was given from gamersgate)
or
2) get access to the software for the standalone version of unity of command (I could uninstall my version in Steam and install the standalone version of the game and DLC). Fortunately it appears that in steam I see "CD" keys beside the game that do not correspond (not the same as) the steam key I used to activate the game. If these separate cd keys do indeed activate the standalone version of the game and DLCs (DLC has a seperate key), this could also be a viable solution. Therefore it is possible that I could install the primary game and DLCs outside of steam. Unfortunately I don't have an actual download copy of the game (non-steam). If so is it possible for me to have a download of the primary game and DLCs made available? I can and will supply my serial keys if requested.
