Hmmm...well, I had to do this in a roundabout manner. I tried to do as you said--do the "save as" option--and the same problem occurred. This time, I saved the file as a txt file to my documents folder, opened it again from there, and then saved it in the data folder for my mod. BUT: when I opened Galciv2 and tried to apply the mod, that folder for my mod did not show up. Any idears?
BTW: thanks for responding!
