Minecraft Forums

For a while now I have been playing 1.5.1 with several mods, such as Biomes O' Plenty, REI's Minimap, Mo' Creatures, Balkon's Weapons, and FML. It has worked fine for months, until today when I tried installing a shader as well. After finding out that the shader was not working, I gave up and restored the .jar to how it was earlier. I am not sure why, but now I get a black screen when I try to load minecraft. I even tried deleting the minecraft folder, reinstalling minecraft, and adding all the mods again, but it didn't work at all, even just FML. I am not very good with modding, so any help would be beneficial thanks
