I have tried it all. Approx 3 weeks ago I lost my ability to connect to Shareaza. I was running 2.4.
Background: Windows XP SP 3 with Shareaza 2.4, Zonelabs Pro, Symantec end Point Protection
All was well then I lost connection to G2 and subsequently G1 and Edonkey
I upgraded to Shareaza 2.5 and no change. I downloaded the clean install and ran it and reloaded but still no connection. I then went through all the instructions to make sure my router was setup correctly (made changes and rebooted), per instructions changed zone-alarm and symantec, downloaeded the TCP/IP modification for XP, followed Old Death's instructions for installation and still nothing. Did another clean install of Shareaza and processed the connection test all (both) came back as connected and green. Problem though is I still cannot connect even though the connection test shows everything is fine. In the network window you can see where Shareaza is trying to connect but they come back a connection refused. Beginning to think my Verizon DSL is being blocked by someone outside.
