Just beginning problems

Hi, i got the Game today.. and first i got issue with no servers.. so i changed to evirma.. then i got the problem that i got in the game with only Black Screen.. ok... i checked the Key X Helps a bit.. but now i was just running around and got stuck between just Stones..

Ther was no chance of jumping with space or to get unstuck so i has to close the game?

Is that commen or did i just don´t get it? I pressed every key on may Keyboard but nothing helps.. it just looks like i got ASDW Controlle.. and Mouse movement.. i get night vision and 1,2,3,4,5.. rawing sounds.. thats it.

Maybe you can help a newbe, thanks
