Well, it could be a problem with your aolserver, what I mean is that you have your directories like:
/bin/
/log/
/modules/
and then you have this:
/servers/
inside you should have the name of your specific server,
/servers/yourservername/
and inside it needs to have
the same files/directories thas has the server1/ (this is the default)
I hope this will help!
