Having a couple of game stopping bugs beginning of game

[BillyBulletz]

I bought the game from GOG. The first issue I had was after drinking the tracer fluid, I left the apartment and the game would not progress. I got the black loading screen but it just stayed there, it never continued.
I started a new game, got past this to the office where I'm to have the scan. I walk to the elevator and there's the keypad. I say something like "I can figure this out. But that's it. I can't move any longer except to turn about, can't move forward or backward, can't click on anything.
