Hi, 3 of my friends and I are trying to play ARMA2 Harvest Red campaign co-op multiplayer. We are all on the current Steam version of ARMA2 and I am the host. However, the saved games do not appear to be loading. If the mission fails, and I choose resume, it loads from the first autosave and the mission can only be started from the beginning. If I choose revert, I see a list of recent save games, but if I select one....it goes back to the mission select menu and once again I can only start from the beginning. Does anyone else have this problem? Is there any fix?

Anybody? No? Bueller?
