Lordaeron Bug with my pj

My character is at this time in the north of the Vega Stranglethorn, was about to go to do a mission on the north coast when I started the game to take and show me an error, try to download the graphics in case it was my pc, but I continued in the same and just now when I try to enter the game remains on the loading screen and does not charge completely, no matter what happens, I need you to unbuckle it as soon as possible please and be responsible to play again
