It's very strange: I play on a modded single survival world, and while playing suddenly it freezes up, I disconnect and get the error "Cannot connect" and am at the loading screen for Multiplayer servers.

Post a crash report if you have one.

yeah it's weird, I went into the crash report folder and it seems suddenly they changed to "server" instead of "client". Here is the report:

please, can anyone help? I still get this error...
