Whenever I try to start the game, it hangs up at the loading screen of the first level. It´s the same when I try to open the options menu.

Tell us more please. Like what version of Windows you have and video card, etc.

-W8.1
-Intel Core i5- 4460 CPU @3.20 GHz, 3201 MHz, 4 CPUs
-Intel HD 4600

i am having the same trouble. The game starts (having a dr reading a note and showing a picture of the note) then just hangs midsection without loading completely. If i press mouse i can hear a gun shooting and someother keys
also ellicit grunts and hitting noises however there is no picture. I have windows 10 but it is running on windows 7 to my knowledge

I have the problem that i can't take the Dynamite in the first Level to continue. I going to the box with dynamites, the player takes the items, but i can't use it when i press 1

I am having the same issue like you guys. Is there a solution to this problem?

Same problem here.

Same problem but windows 10. Sound continues in background but have to restart PC to get out, nothing else works.
