Google ffxi error 3001. It's a fairly persistent issue that's existed for a number of years. Some claim work arounds and fixes such as resetting your router, complete shut downs, full reinstalls, etc. Personally, I've had it happen twice over the past 2+ years. The first time it took 2 days for the issue to work itself out, the second I had a friend log me in and move my character. AFAIK, there's no real "fix," it just happens. The explanation I remember reading said it was something like your connection to FFXI was still in tact through your ISP, and until that connection was reset, you were stuck.
