Ok this doesn't have to do with my Minecraft client. that works fine. i downloaded the mod SinglePlayer Commands and installed everything correctly (i am great when it comes to installing mods for Minecraft) and I placed WorldEdit in /.minecraft/bin/ folder just like it said to. its an Executable Jar File just like the Minecraft is in the bin folder. so i click on WorldEdit and a window pops up saying A Java Exception Has Occurred. I'm running Windows 7 x64 bit Dell Ispiron Dual Pentium4 chip inside. all my drivers and software are up to date. so whats the issue with Java?
