Game crashes

Hey guys =)

I have an annoying problem…
first sry for my bad english ^^

second: Usually when i log into the game…i can play for about 3 or 4 minutes…but then i get kicked from the Server and cant log in again (so restart the game)…
While the game crashes i can run around and shit but i cant use anything in my item bar and cant open chests or something else…

Someone has the same problem?

Hope you can help me =)
