Well, it looks like the service is not started. There is nothing listening to the port 3312. Doesn't mean that it's not indexed, that would be a cronjob anyway I guess. It's just a question of either opening port 3312 on the server or more likely do a service search-engine start, which takes only seconds.
But I take it you still did not get hold on Horse, thus you probably don't have access to the server. Am I right? That could mean it can take a few months until he bothers to check in.
