Game Crashing Constantly

Hells-Msngr

It seems when ever I enter town and theirs that crowd of people all in a bunch spamming chat and what so ever my game laggs for a few seconds, locks up and then I have to alt tab out to reach the send error report message... Then it  just closes reguardless if I click yes or no. So it crashes; I tried seeking help at Last chaos's official forum but no body seemed to pay any attention. Could anyone help me with this? Ive got a gig of ram, I've got a fully updated ATI Radeon 300x/550x/1050x series. Its got 128MB of VRAM. I've set my card settings to all best proformance, Ive made the games graphics go as low and freakin possible. Disabled my anti virus witch is avast. Ive redownloaded and reinstalled the game. Made sure I had all windows updates. It almost tempted to go flame on Last Chaos's forums about how 'crappy' their game is, I know for a fact this game shouldn't demand so much. Because you know what I can run World of Warcraft with 10x as many people crowded in an area and not lagg at all. I blame just crappy game developement.. My friend plays this and its something we could do to spend time you know just goofin off so I don't want no offended fansboys telling me to go play WoW I was just using it to show a point; I don't like WoW all that much.
