There are no pk4 files in the fms folder, besides within the specific mission folders. I looked for Mission of Mercy and William Steele 4, the last two releases. I just don't understand what could've happened. I literally just updated to 2.06 and all the missions that have been in my list since well before release 2.0 are just gone. Is there a way to backdate to version 2.05 and see if that helps. If not, I'm sure downloading the game over again might do the trick, and just keep the FMs folder intact.
