Guild Wars 2

hey, today (8/9/2013) there was a recent build today that has messed up me allowing to log into gw2 today. I dont know why but when i login and press play, the black screen for loading up gw2 keeps freezing my computer. Friends have told me on vent that they are experiencing wierd stuff while playing the game such as wierd graphic errors ever since this recent build. checked if it was my computer and played other games and there have been no problems. it is only when i log into gw2 and press play does it freeze my computer.

Have you tried deleting the local.dat (under my documents/guild wars 2)?
