Suddenly I am now unable to join my friends server. When ever I try to log in, it gets stuck on the "Generating World / Locating Server" screen. I let it sit for awhile and it still wont let me in. Ive logged out of my account multiple times, reviewed my settings and I'm still not able to get in. Once I tried my other account on the same server though, I was allowed right in. I never messed with my main accounts settings, so I dont really know what I did to cause this to happen. In my friend's POV, it never says I joined the server, but when I hit cancel, I leave the game. It also counts me as an online player. Please help. 

(The photo of the server status is when nobody was online. The one person "online" was me trying to get in.)
