Return of Reckoning

Hi! I have a problem with disconnect at T1 warcamps (only dwarfen and greenskins works normally). I have this disconnects when downloading warcamps (log on, resurrecting, or using fly master) and again again, i have only chance to try run out of warcamp or will be disconnect and disconnect again.
I`ll try to reinstall client, change graphic options, off addons. Nothing helps.
