I swear to God I have played Hex Empire 2 before, so theres no way that the game is permanently lost, but I'm pretty sure that all their servers for the game are dead.
On the topic of Hex Empire 2, during my search for a working version of it I found a version of the game on Miniplay.com. The game displays a loading screen, but then gives an error message saying to email firstname.lastname@example.org. Have you ever worked with come2play.com?
Lastly, do you still have any of the original .swf files for Hex Empire or Hex Empire 2?
