Disconnected from server when connecting

[mc.crab]

Whenever I try to connect I get immediately disconnected. Server is running Infinity 1.3.0 Other players are not having any problems. Everything was working just fine until it suddenly started doing this.

This is what the server log says when I try to join: http://pastebin.com/it4Z2YuU

And this is what client log says: http://pastebin.com/wkrsiEiu

I have tried both the FTB Launcher and the Curse launcher and redownloaded the packs twice on both launchers.

When I got disconnected for the first time I placed down an MFR Plastic tank. I asked another player to place one and he got disconnected. Here is the log: http://pastebin.com/0miZuiSb

Edit: Fixed it, used McEdit to find the cordinates of the block and removed it using setblock plugin.
