I have the same problem. I googled "server.met" as suggested. There was no server.met file already in the aMule folder,
so I simply dragged the downloaded file to the aMule file and restarted aMule. Still no connection.
I've also tried clicking on the "download server list" arrow, but I get the message that it failed to download.
I have used aMule previously with no problems, so although I'm no tech whiz, I'm not a newbie to aMule.
What am I doing wrong, or not doing?
