I hate to double post myself, but I still need help if anyone's willing.
Anyways, it looks like very few people are still playing this game, considering this thread has come to a halt. Makes sense, as it's story-centric, and there's no reason to go back to this once you're done.
I've still been trying to get past the part I'm having trouble with, but no luck, and it strengthens my assumption that this could be a glitch (most likely caused by the new OS, as no one seemed to have trouble playing the game when it first came out).
I'll still try a little longer, and wait to see if anyone posts, but if not, I'll leave a review warning others of this game stopping glitch. It really sucks I won't be able to continue this game.
