Ohh, This used to happen to me too!!
You open it up and the black screen just stays there?
Aiighht This is what you gotta do man!!
Trust me this happened to me before!!
Re-install soldierfront
And then start sf up,
when the black screen appears do not touch anything leave it there.. SF WILL COME ON!!!
But it will take some time!!
It will say not responding but dw it will come!!!
Mine went from waiting 5 minutes each time with a no responding thing for black screen to now just takes like 30 seconds or soo before i get on!!
So when black screen comes on, do touch anything just leave it there!
