I downloaded and tested it. I have the same problem with the exceptions. In my case it seems to have something to do with a rat (?).

I get constantly messages like:

Access Violation
Error in TClient.OnReceive message='OBJ RAT POS 202383 442.00 619.00 180.00 100.00'

Character name was 'doh' and system is Windows XP Pro SP3.

Hope that helps
