Guyz i have found an article to solve TERA crashes and error, hope it will help you. http://www.guide4games.com/index.php/news/1779-tera-pc-crashes-freezes-crash-to-desktop-ctd-black-screen-low-fps-cant-launch-sound-error-client-crash-fix-download-error-xmllitedll-error-fix-general-failure-error-stuck-fix-connection-issues-and-fixes
Was this site translated into english by an online translator or something? It's extremely hard to follow given the technical details of the situation. I was hoping there was a good fps fix in there somewhere, but I could hardly follow a sentence from that website.
