Thanks for your reply. I have win 7 Pro 64 bit, but I don't think that is the problem. The Editor sees the mission in the list of all of the other missions included with the program. I can save and open, etc. all the things I expect. BUT, when I go to the main menu and select Mission, my mission is not in the list. And, when I use Windows Explorer to check the missions, my mission is not in the list.
One late bit of data. If I start FC2 as Administrator, my mission doesn't even show up in the Editor. So, I will try again as Administrator and see if the mission will show up where expected.
Thanks, Jim
