Been getting this error near constantly, and only started getting it after patch 3.5 hit. Along with this, I have a lot of models not load in, for example when I was doing Palace of the Dead, between floors 80 - 100 none of the mobs models loaded in, and only some parts of the map loaded in too, making it really difficult to play.

I have restarted my router multiple times (even phoned up our provider), restarted my computer, uninstalled and reinstalled the game, made sure firewall wasn't affecting anything. I am not sure what else to try, does anyone have any idea if I can fix this?

I also occassionally get error 2002
