1- There are two "Save Here" slides. Choose the second one, and save there, not before.
2- Part 2 MUST be installed in a separate folder. Not ever over part 1.
3- Start Part 2, choose Load. The save from Part 1 with the Save Here Slide is the one to choose.
4- If something goes wrong, you can rebuild your save, by choosing Start and answering a bunch of questions related to the paths you chose in Part 1. It's tedious, but works. If you don't remember who is who, in Part 2 you have a full roster of everyone to refresh your memory.
Good luck, hope it helps.
Peace
