Only Goes Up To Welcome Screen

[ChernobylGal86]

I recently purchased Amnesia: The Dark Descent from Steam. After purchasing it and installing it, I found that it would only load up to the welcome screen which says,

Welcome to Amnesia: The Dark Descent

What follows are some quick messages on how to get the best possible experience.

Then it doesn't go any further. Another thing I find was that my mouse wasn't moving smoothly and was cutting out (disappearing and then reappearing).

Thinking my computer wasn't used to it running, I restarted it and tried again, which I have been doing nearly everyday hoping it will work. When it didn't seem to fix the problem, I came to the forums and tried updating my graphics card. After doing that, I launched the game and the same thing happened. I've made sure the HPL file is in the correct place and I've also done a Steam Integrity check on the files and they were fine. I have also attached the HPL file below.

What I have:

A laptop with a 64 bit Windows 8.1

Thanks.
