with login!

hi there guys!
Well... I've been setting up a server on my own so I've got stuck!
that's what happened... everything was just fine... till the server list comes up and....
NOTHING HAPPENS! well... I've took a screenshot after I've clicked the sierghardt server (the running one...) and still nothing, just makes the clicking noise and nothing else...
anyone knows why this could happen?
