In-game Crashing

Anubis

<div class="IPBDescription">Game keeps crashing in game during play</div> The game keeps crashing on me during play and sending me back to the desktop. I downloaded the game when it first came out and this didn't happen durning play. Then, before the server patch came out it started happening, I don't know why and after the server patch it continues to happen. Any ideas as to why or what I can do?
