I deleted all data from my computer and re installed windows. But still tanki servers kick me out after 5 min :?

i have 20mb cable internet, and the servers i choose are not full. Server with 1600 players kicks me out. i think the problem is in my pc, but i don`t knew where to start search.

Before im kicked out, the game appear to be brake down. Then comes writing "connection closed by server" And only thing left to do is log on again. This happens after every 5 min :?
