Still struggling.

I am using a old P-III computer running Ubuntu 10.10 maverick, I followed the exact procedures provided by Mad-scientist:

1. create a password for root;
2. install java stuff;
3.restart firefox 3.6.10

My problem is installNC.sh is not runing when start firefox, but I am able to log into my company's VPN network and check email which is located under "web bookmarks". But when I click on the icon under "terminal sessions", it gives me "The terminal session is not supported on your computer".

Any ideas?
