wu-blast error, no valid context

[pludder at my-deja.com]

Could someone tell me the reason for the following error message when
running Washington University blast 2.0a blastn:

Exitcode 23

Fatal there are no valid contexts in the requested search.

warning: the maximum achievable score of 5373 in context 2 (frame 1 ) is
less than the cutoff score 82


Any pointers to a more suitable newsgroup would be welcome as well
