Minecraft Forums

Okay, so the other night, I tried installing ModLoader and other mods, and I guess i ed up. I deleted and reinstalled minecraft.jar at least 3 times, but no avail. I finally found a MinecraftLauncher.jar file up for download, so I downloaded it. It appeared to work, but everytime I tried making a new single player gamefile, It either told me out of memory, or it just stayed on the "Loading, Building blocks screen" for 20 minutes and didn't do anything.

What I did next, was i tried going back to the minecraft.jar file I had installed before the launcher, and everytime, I get this stupid message:

Jar Launcher
The jar file "minecraft.jar" couldn't be launched.
Check the Console for possible error messages.
<OK>

So I check the console, and I get the following:

java.lang.NoClassDefFoundError: org/ wjgl/LWJGLException
Exception in thread "main" java.lang.NoClassDefFoundError: org/ wjgl/LWJGLException

(WHAT?! I have no clue what this means)

This is really making me upset, considering that Minecraft is the only game I have for this old hunk of junk.

Please help me restore my Minecraft!!!

First, backup your 'saves' folder and delete the entire Minecraft folder and force an update in the launcher.

If you still have problems, try the auto-updater on this page.

How do I force an update?? <8o

Launcher>Options>Force Update.
Then log in and let Minecraft redownload.

I dont appear to have that specific folder <8/
