Ok seems like the latest Unstable build 573 has worked out some of the issues with build 494. Last night I was able to join several servers in multi player without issue. Get mod seemed to work on almost every server with a couple exceptions. I have setup a dedicated server with Jops for people to test out. The name of the server is Jops2009TestBuild573. I will keep the server up for a few days for people to test out the unstable build.

oops! Mistake on my part. I have also posted in the proper forum. Thanks to the forum police for pointing out my mistake.
