While that question had almost NO information, I'm going to pull at straws..
1) WHERE is the error message?
2) What are you doing when you get the error message/
3) have you patched to live?
4) What server are you connecting to?
5) Does 303 I don't see anyone by that name around here... fit?
6) Thats from my eqstr_us.txt, assuming you see it in the client
