Exception in thread "main" ??

[rio44]

I downloaded the dw20 1.6.4 pack, but every time I attempt to launch it I get this error report. Obviously the most pertinent information is at the bottom of the log. Is there a fix for this? I've tried erasing and re-downloading everything, but that didn't solve anything.

Sorry about the original lack of formatting, I read Jaded's before you post and completely missed yours..

Also, it appears to only be an issue with the new 1.6.4 packs, the old dw20 pack works just fine..

You need to complete the guide again. You did not update Java correctly. You may need to manually uninstall Java then reinstall it.

I have no clue how you figured that out so quickly, but thank you. Re-installation solved the problem.
