stand-alone blast problem

[tujchl]

HI all:

I used stand-alone blast (2.2.25+) to alignment some sequences (~50,000 and 150 bp for each sequence) to human genome under win7.
But I always resevieve such err message:
"blast database error: sequence not returned"
and have no blank output file.
could you please help me?
Thanks~~
