The first message is a minor issue and you can just ignore it. In CVS this message should no longer produce a dialog requiring your intervention, it will just be a message in the log. The hostname in question is not the server's, it's your computer's.
The second problem is due to the fact that gruk.org is no longer serving a server.met file. So, when aMule tries to download it, it gets an HTML page explaining that the server.met is unavailable instead of the actual server.met. Google for a different server.met URL and use that.
