Hi everyone! I was looking for a games server and I found this. I have seen videos, and I see that it's good, but I have a little problem... I can't enter. My MC crashes, I don't know why. I've been deleted my .minecraft and that things, but that doesn't work! If this helps, I have: Minecraft 1.7.9 Minecraft 1.7.9 (W/ Optifine) Thanks!
