Things started off fine, but it seems as more people are joining that the servers are experiencing some stress and causing kicks. I am doing my best to resolve these issues in a timely manner so please bear with me.
I believe that most of the problems are resolved in version 2.0.3.4, which is now available for you to update to.
Edit: Please keep in mind that for people to be able to join your server it needs to be port forwarded, otherwise they will get a timed out error.
