I will try both suggestions,I don't know when I attempt to restore oe map will it ask me to save the fullsac map.Thanks though for your help.
Maybe you could contact Steve C. at TTS.....also, read all the help files pertaining to the saved files and where they are located. I keep all my TTS files in one folder, better to access them.
When you load a new map, you still have the original one in your map list files, you can rename it to whatever you like (there are suggestions in the help files) When you do the TTS updater, you will also get a list of maps, some will be similar to your setup. Take some time to read the instructions, there's a bunch of info there, and it takes some time (for me, at least) to figure it all out! This is a very sophisticated program, and it does take some time to get used to it.
I hope this helps a little.
