I think I see what I did wrong. I tried to copy a data file from an older version to the new one to try and carry over the save file, but it seems it basically just meant I kept playing the previous version of the game. Shoot! Well that explains things at least. And you're correct, it doesn't seem I can carry this save to the new one the usual way. That is a shame, but hey, least I have a new version of the demo to enjoy some time soon. :P
Thank you for the help!
