I open it in winrar (I don't extract it) and select all the files and drag 'n' drop them into my minecraft.jar. Am I doing it right? It crashes my game when I try to use it.

Does your show a black screen where the "Mojang Specifications" logo is supposed to show up?

No, I know how to handle that. I get an error in game, after doing no particularly significant actions (just running around). If you think it would help I could post the error message.

Ohhh. I think I know what the problem was. I just read that some mods may conflict with Risugami's modloader, and if they do it could cause my game to crash. Is there anyway I can get around this? I'm not sure which mod it might be, is there any way I could find out?
Edit: I think I found it. The light sensor shares a class with the modloader.

Oh, can you tell me possibly how to handle my error?

Go into your minecraft.jar and find the metainf folder. Open it, and delete everything but the manifest file. (should be deleting 2 files)

I had already done that -___-
