[Black Screen (Single Player Mode) Please Help!!!!]

Title: Black Screen (Single Player Mode) Please Help!!!!

Version: 1_0_3

OS: I have an IBM laptop, and am using Yogbox inside of Tekkit

Java Version: I honestly am not sure...

Description of Problem:

My Mojang and Yogbox (the mod pack that I use in tekkit,) opens perfectly, but then when I open my own server in single player, I get a black screen. I can see the hot bar and the mini-map, but I can't see the screen. Also, it doesn't let me force quit, I have to manually shut down my computer everytime I enter my world. Furthermore, the last thing I did in Yogbox was cut down a large tree with a stone axe. Could that have caused it? I legit spent 4 hours yesterday trying to restart my computer and I even downloaded it again, and nothings working! Please help me, i'm desprate. I'll try anything!! Please ask me anyother questions if needed.

[Cannot connect to my own server but others can]

I have a problem somewhat to that extent. My Mojang and Yogbox (the mod pack that I use in tekkit,) opens perfectly, but then when I open my own server in single player, I get a black screen. I can see the hot bar and the mini-map, but I can't see the screen. I legit spent 4 hours yesterday trying to restart my computer and I even downloaded it again, and nothings working!
