Greetings, Knightstrike!

Thank you for your patience while your report was investigated. According to our development team, this issue may be resolved by reinstalling both the game and the PlayOnline viewer. If you continue to experience issues after reinstalling FINAL FANTASY XI, please resubmit your report with information regarding your PC specs, OS version, and graphics card, as well as specific details regarding the conditions that the client has crashed under (such as if it took place during a fight, a warp, an area change, etc.). Thanks again for your patience and cooperation!
