I did a clean install of AH because my frame rates had become unstable, ie: 15-30-57-58-61-59-35. The clean install took me back to a stable 59-60 so that problem solved. But now I can't see my offline missions under Pratice Missions on the offline clipboard. I have the terrains needed and I can see the missions in the missions folder ( Hitech Creations>Aces High>missions ) Any suggestions on how to fix?
