thecalaba server problems

hey guys, ive been having trouble getting into the server lately. This started with a chest in my lot (14) that every time i right-clicked on it my screen would go blank then minutes later said "disconnected from server". i then tried to get rid of this problem by breaking the chest. Now every time i try to join cobble creek i just get a blank minecraft window.
if anyone knows the cause of this problem or how to fix it; please contact me.
cheers, thecalaba
