So, install the new game, and migrate the saves from the old version, but be careful you just want to move the saves not the ini-s or is it global save?, that can cause some confusion. (but honestly the game isn't that long, so getting back where you left off isn't so bad, I've started this game 3+ times to see all the tidbits that have changed...)
If the saves don't register, move the other files located in the old save folder over. (but I hope someone else takes the reigns, bc I get mixed results pending the game engine.)
Hope this helps a little.
ALSO BIG PROPS TO BREADMAN for all the live tech support in the thread lately. Hope you are getting some sleep, bouncing between this forum and making more for the game!
