Okay so I had the same issue and I was able to fix it. Every time I tried the "talk to" options, the game gets an error and the exception message pops up.
Turns out the issue was because the game was inside one too many folders.
Due to the way I extracted the files, all of the game files was put inside an extra folder, which wasn't necessary and fucked everything up (don't ask me why this happens, idk). To fix this, just copy & paste everything from the extra folder inside to the outside, and delete the original folder.
I hope this helps.
