so i haven't ran my minecraft server in a long time and i just got on today cause i wanted to play and when i try to run my server it says "(my server ip) lost connection" and it keeps saying it and i cant join.. im running the server with HAMACHI and it's working but the server won't..

p.s i noticed people have had this problem before but i've googled a lot and haven't found anything that will fix it.. please help!

p.p.s i just updated "minecraft" to 1,3,1
