I am new to this private server, but I played plenty that used Hamachi. Judging by the network entrance, it says that they're all full for me. I even went up to dragonballz1009 and apparently it went as FULL. If there's anything you can do to help or fix it please let us all know.
0000, 0001, 0002, 0003, 0004, 0005, 0006, 0007, 0008, 0009 appear FULL
Let me/us know,
