OK, I'm still having the same problem.
I found this info on suns site
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6303969 it describes EXACTLY both errors I'm getting.
However, I don't have a clue what it is saying.
I got the firewall part, and turned it off, still no luck.
This isn't a new install, I've used this debugger many many times.
Several times on this very assignment.
Do I maybe need to reinstall my JDK and JRE?
Thanks
