I'm pretty sure it works if you do it. And you never did tell how much RAM you have and whats your OS.
So anyway. Its the walkthrough mod that keeps crashing your game. Easiest solution is to don't use it. BUT if you used it and games keep crashing it means it messed up the file called "persistent" in your save folder. Now thats a pretty important file. So it doesn't matter if you start a new game, if that file is messed up it will keep crashing.
So the solution is that you delete the persistent file. There is both of those. In both save folder. One save folder is within the game's directory. The other is in the C:\Users\<yourusername>\AppData\Roaming\RenPy\BeingaDIK folder. You may not see this location because the AppData folder is by default hidden by windows. You can set it to appear or you just simply manually write the location into the header, that will open it for you.
From there delete the whole BaDIK folder. With saves and all. Then detele the game itself. With saves and all. Re-extract it. Launch it. This will create a new persistent file. Forget the mod (for now) and try if it keeps crashing on you or not.
