How Do I get WeCUI on my tekkit client?!

[fallenlovex]

I have WorldEdit 5.4.5 on my server and my technic launcher is the latest and I've tried putting ModLoader 1.4.6 and ModLoader 1.2.5 into my minecraft.jar, the same with the WorldEditCUI.zip both 1.4.6 and 1.2.5. All versions give me the error of "Minecraft has stopped working" after I click the Login button on the techniclauncher.

Any Help?

First of all, clear your Tekkit cache to get your original minecraft.jar back.

Put CUI in modpack.jar instead of minecraft.jar.
