Anyone here use Meez? Possible java problem?

I'm guessing I'm having another java issue, but I don't really know. I use meez.com, and haven't been able to change my avatar on there for weeks. I can log into the page, and I'll click "change my avatar", and it never finishes loading. The avatar should load with a java applet (I think), and the load bar gets almost to the end then freezes. I thought it may have been a Firefox issue, but it won't load for me in IE, either.

I checked my java, the site says I'm running the latest version. I uninstalled MySpace Mozilla, so that's not the problem. Anyone have any ideas? Thanks a ton!
