I just downloaded the new OS update to 10.1.5, and it really performs great. BUT, I can't run LimeWire now for more than a couple of minutes without it crashing. I looked at the console log and I get the same note about the Rulebook Server before it writes to the crash log.
So far, all my other apps run just fine, but my poor LimeWire just can't deal with it.

Is this program going to get better, or is this just as good as it gets? Somebody said it has to do with Apple's version of Java, but whatever the reason, what can we look forward to?

This is a darn shame. I love the program.
