1. Are you using the Titanium client?
2. I also used to crash a ton, it started sporadically at first but after a while it escalated to about 70% of the time I would try to zone I would time out and crash. Tried using wineq, removing my characters info file or w/e and nothing would work. Funny enough, both times (last year and when I reinstalled a couple months ago) I managed to fix my crash issue by
installing the updated zone textures. I still very rarely crash but it really only happens when I try to load these heavy ass tree zones in kunark while I have torrents and streams sucking up my bandwith.
