Black screen after installing mods [closed]

Minecraft isn't working and just gives a black screen. My wifi is working, so that's not it. I've tried running it over and over again, but it's a black screen every time. I've only installed Rei's Minimap, and Minecraft worked before that.

A black screen after installing mods is usually caused by forgetting to delete the META-INF folder from the jar. Modded Minecraft will not run so long as that folder is still present in the jar.

Reopen the jar file, find that folder and delete it. So long as the mods are for the right version of Minecraft, it should run now.
