You can follow the progress of Shareaza on Sourceforge..
SourceForge.net: Shareaza
For your connecting problem..
I'm assuming that you had a connection previously, but to save going down the wrong road, do the connection test here..
Shareaza Connection Test - Atomo64
If that fails, then you have a Router or Firewall problem
If you pass, then try this...
Hit F9 to open the Discovery Services window, then query one of the GWebCaches by right-clicking it.
Then Hit F8 to see if there have been any hosts added to G1 & G2 host cache.
If there are none, go to -
Gnutella web cache scan report
Right-click and copy one of the Caches then add it to your Shareaza in the Discovery Services window, then query that..if it doesn't work at first attempt, try adding others.
Good Luck
EDIT: One thing I forgot to mention.. when you get your host cache filled up.. Disconnect from the network and Reconnect
