I was previsouly able to save my Warcraft II games but they disappeared today. After uninstalling and reinstalling the game I still can't save my games. (I "save" the game, but when I exit the program the saved game is gone when I come back.")

Any suggestions? Any contact for Good Old Games Customer Service?

You can talk with them about the WCII issues, and see what can be done in your situation:
