+G is correct. The campaign takes place in the Azerbaijan region. CD1 only has the NTC area maps. It needs the second CD to decompress the AZR maps. I generally keep one CD mounted and if I want to switch theaters, I mount the other one. Either CD will allow the game to work.
Recluse
Something more is going on. I can do a single mission with the original disk in, exit to desktop. Remove the disk and mount an image and try to start the game and I get the "No CD" message. Then immediately put in the original CD and it will still give me the "No CD" message. The only fix is to copy my whole backup (thanks for that tip) Longbow folder to the Janes/Longbow folder. It is like some flag gets set after trying the mounted drive and it will not go back to the original CD.
The good news is I can play the game with the CDs and I can poke around with the ISOs in my spare time. Thanks for all the help.
