The issue is I don't think you have the full game, the files are named different, and the splash screen of the game is different. The developer followed a pattern with each release, the splash screen always had the version number in it. Most versions had a different picture on the splash screen for each release differentiated them. If that was the final version of the game my cheat mod would work with it without issue.

, most of the versions had a unique splash screen for them, he did this quite often, it just turns out in this case the are the same picture. The picture I used in the OP of this thread was from the splash screen of ver 12, you can tell because it says it's from version 12 on the picture.
I know you believe you downloaded the final version of the game, with all of the evidence you have shown me you haven't. If you had the the files structure would be exactly the same, only the file size would be different. If you have the final version the cheat mod would work without issue.
Unfortunately I can't help you make that version work with this cheat mod as I believe it is not the final version of the game. Just because another site says that is the "final version" of the game compressed, does not make it so. I know this site has links to the final version of the game, and I know the cheat mod works with the version without issue, every now and then someone has a problem with the mod, but in all the mod has been very problem free with each version of the game released.
If you are having problems completing the events and following the walkthrough, those questions should be asked in the game thread, this thread is for issues with the cheat mod only.
