Any time I attempt to load a class in mxj or mxj~, Max 6 crashes. For example, opening the help file on mxj~ crashes max. I'm running windows 8...Could this be a problem from the java side, or will I need to try re-installing Max?

Version 6 Update 27 (build 1.6.0_27-b07) 

It shouldn't crash - but perhaps your Java is 64 bit.

You can install multiple versions of Java, maybe this will help.
