I have a huge problem.

Since about 2 weeks i can't do anything. Everybody and me have a ping of 0. Other ppl say i have a normal ping. But i can't use anything in my inventory. I can't use items, and when i try to do a right-click on my items there's just written "reveiving..." all the time. But nothing happens.

Before a minute i've tried to get killed by a zombie, but they don't react too, so i can't even try to reset my character. Please help me, i want to play this game :(
