Problems entering the dbog

I don't know why but I keep having problems with dbog every time I enter the game everything is fine but when a while passes or I use the tp the game crashes quickly and kicks me out and so on. I play for a while and it kicks me out.

No, I haven't received a single patch yet.It's just that the game cuts off after about an hour or when I teleport it kicks me out automatically with a message like this:??????
