Hey there! I haven't played for some years, though I did grab the last two expansions on Steam when they came out in expectation of this day.
The game works just fine on my windows machine... but I've got a bit of an issue on my Mac... Steam refuses to install on a Case-sensitive HFS root! This means I cannot install or run Steam on my mac!
Now, I can't remember how I originally ordered the game, but I do have a text file in a backup that has all my keys except for the most recent two expansions. I then realized that I either bought them through you direct, or via a humble bundle - and I later added them into steam. Though, the last to expansions were purchased straight through steam.
Doing a bit of googling indicates that you used to be able to right click AI War in your steam library and view your keys for in-game activation. This seems to be gone though, and I guess you handle it through steamworks now?
My question is, do I have any way to get the missing keys out of that mess so I can run the game from the unlockable demo on my Mac, since Steam refuses to install and the files pushed down by Steam on Windows seem to lack files for the other platforms. My settings.dat has a LicenseKey field with some data in it, but the ExpansionLicenseKeys field is blank.
(seriously, so irritated at steam about this. there's zero reason for Valve to just not support a case-sensitive filesystem these days, because Linux is supported and nearly every filesystem used in that environment is case sensitive as well).
