Black Screen

I have minecraft 1.7.3 with Mo'creatures, single player commands, too many items, modloader, audio mod and guipdi thingy. After I copied and paste the optifog and optimine things to the jar and i get a black screen. any body knows the reason?

Im pretty sure you just cant have certain mods with each other or they dont work so maybe get rid of what you put in for the optifog

heres a solution delete minecraft.jar and run minecraft.exe and woop all better
it does get rid of mods tho soo
