Minecraft Forums

Ok, so I've been trying desperately to install my mods for 1.4.5, but I keep doing it wrong and I don't know whats making it crash but it is. i have 7 specific mods I'm trying to install, but i only get about three or four down and minecraft wont work anymore. I think it has to do witht he order I install them in, it seems like thats what somebody told me sometime ago. The order in which I install these mods are as follows.

Modloader
Optifine
Single player commands
Worldedit

And minecraft crashes when I try to start it after installing worldedit. This is the error message I get...

If anyone can help me, it would be much appreciated.

Not sure this is the right forum area for your post. All of them work when installed, except WorldEdit? May be something incompatible with WorldEdit. Are you installing WorldEdit by itself or the one that comes with SingleplayerCommands? try installing them without optifine.

ther might be a conflict between optifine and singleplayer commands and this is the wrong forum bud

Ok, problem sovled, I just reinstalled everything from scratch starting with modloader, then spc, worldedit, theeeeen optifine. Sorry for the misplaced post btw, but I was a little agitated when i posted this last night, not to mention tired, and thanks for help everyone. And maybe I should have been a bit more specific RevanBlade, but I was trying to install Worldedit CUI, not the base worldedit that is usually included with spc.
