After playing for a few hours yesterday, I accidentally hit some keyboard combination that loaded a previously saved game. All the progress I had made was lost because the last saved game I had was hours earlier. At any rate, if anyone can help me with a save file right at the beginning of Part Two, just after Rufus and Goal leave the town and get to the mine entrance, I would appreciate it. Thanks.

Thank you! Once I figured out that I had to use the command line to change the file extension, it worked perfectly. Thanks again.
