SQL Server Merge Replication - No subscription is on this publication or article

I have setup a merge replication publication and added a subscriber but when I view the synchronization status I just get the error message: "No subscription is on this publication or article". Looking through replication monitor shows this as an Error 14050 but I haven't been able to find much detail on why this is happening. I had the same tables replicating using transactional replication without any issues, but need to use merge since the subscriber gets updates that need to push back to the publisher. I have tried turning on verbose logging but it's not writing a log so I can't tell what's happening. I have also tried deleting and rebuilding both the publication and subscription but continue to get the same message. What do I need to do to resolve this? Thanks
