crashing!

[warlordmaster]

I tried to install single player commands for world edit and made it so every time i go to a new world it goes to saving chunks and stays there. so now I can't play tekkit pack!Is there any way to fix this. I tried to delete the single player commands files but that didn't work!

You mean technic because tekkit is the SMP version of the technic pack... BTW i know it's a stupid step but did you delete META-INF directory from minecraft.jar?

all of the following stuff is officialy put in (ModPack.jar) thats where ALL the mods of That Mod pack is,
