Getting kick from the game when launch abyssal

Hi,

When I’m launching with my main (T3) the abyssal dungeon Hall of the Twisted Warlord, am getting kicked from the game (no error message, just a shutdown) then when I come back no entry count is used fortunately and got back to the city instead of the dungeon. What should I do ? (worked after the 3rd time, but its still an issue to be recorded)
