Hi,
Same problem here, aMule SVN using wxGTK2 v2.8.4 (1/6/2008) on Gutsy, I think that it is a problem with auto connect on startup, when I click on a Server it connects to, but never works auto-connect or re-connect on loss.
2008-01-07 12:49:40: ServerList.cpp(171): 17 servidores encontrados en server.met
2008-01-07 12:49:42: amule.cpp(806): Conectando
2008-01-07 12:49:42: ServerConnect.cpp(111): No hay servidores vĂ¡lidos en la lista de servidores
For me, it is solved going to "Preferences-->Server" and un-clicking Auto-autoupdate serverlist at startup, now aMule tries to connect everytime to a server.
Happy new year!!!
