urchin 6 import error

[tweidman]

hello-

i have a custom lookup table and some filters and every time i process
them through urchin i get this error:

[16:00:56] Post processing data for 200907
sessions: 100 (0%)
ERROR: (8018-758-699) Invalid record

i'm running urchin 6 on windows 2003 server. any help/input would be
appreciated.

thanks,
