Ok, I get a mod and it works in singleplayer. I then go over to multiplayer, but when I craft the item and click the finished product it closes out my Minecraft. I was trying out the Revolver mod with ModLoader (both installed correctly) and when I tried using the ModLoaderMP for multiplayer I got the black screen of death upon logging in. I have searched Google and Youtube for hours but I can't find a way. If anyone can help I'd appreciate it.
NOTE: If having BOTH Modloaders installed at the same time screws it up, please tell me.
