Ok ok I meant as in I click the Technic Launcher and go into Tekkit multiplayer and it says out dated when joining a server. P.s Is there multiplayer mod for Yogbox?

Hey everyone I made a server about two weeks ago and me and my friends played on it and yesterday I wanted to do it again but it kept saying " Outdated server" I downloaded technic server and launcher, updated normal minecraft and re downloaded Java 7 and it still doesn't work :C Any suggestions?
