amnesia crash

[QuesSanity]

I'm not sure if this is a problem with Amnesia but, while playing Amnesia Custom Game's the Game will pop down into the Game Folder in the Task Bar, my Mouse Pointer jumps to the uppermost corner (left side of Desktop Screen)And, freezes there.
It only happens while trying to play Amnesia and, the Amnesia Custom Mod's through Dark Decent.
I downloaded several but, I've only tried playing "A Late Night Drink" so far.
I haven't been able to get very far in it because, of the little Problem I described in this Post.
I'm running Windows 8.1, 64bit, 7.77GB left in RAM.
So, is this an Amnesia Game Problem?
A Problem with my 8.1?
Not enough RAM?
A Problem with the "A Late Night Drink Mod?
Or, the infamous "SOMETHING ELSE" type of Issue?
