I've installed Forge for the 1.7.10, I've prepared mods and also schonmal tried to play. It does not even open Minecraft, but always says:
It looks like you're using an unsupported, modified version of the game.
Here's the reason: Error: org.lwjgl.LWJGLException: Pixel format not accelerated
It could be due to the mods. Some mods would have some suspicious lines of code contained in (hack) clients.
Does that happen when you try to enter a world or a server or does it happen before Minecraft even starts?
Ne Minecraft does not even start
Could you also say which ones are when you see these mods?
Then unfortunately I have no idea… How is the whole crash report?
No. Also had the problem. Stood:
"It seems like you are using a modified version of the game"
or something like that. Modified is Mojang Hackclients.
