Problem With Blastp Of Biopython: Returned Non-Zero Exit Status 1

I want to do a local BLAST using blastp from the Bio.Blast.Applications. However, when I run it I get a runtime error: returned non-zero exit status 1. According to the manual it is
Exit Code Meaning: 1 Error in query sequence(s) or BLAST options. The query used is fasta format protein sequences.

The command line I used, with the BLAST options, was:
'>>> print blastpcline
C:\Program Files\NCBI\blast-2.2.24+\bin\blastp.exe -query "C:\Documents and Settings\newintern\Desktop\Microproteinsniek\arabidopsis-HD.fasta" -db C:\Documents and Settings\newintern\Desktop\Microproteins_niek\arabidopsis-smallproteins.fasta -out test.xml -evalue 0.001 -outfmt 5

Anyone know how to fix that error?

Thanks
Niek

edit:

RuntimeError: Command C:\Niek\blast-2.2.17\bin\blastall.exe -query C:\Niek
\Test\arabidopsis-HD.fasta -db C:\Niek\Test\arabidopsis-smallproteins.fasta -out
test.xml -evalue 0.001 -outfmt 5 returned non-zero exit status 1

I changed it to a path without spaces, still gives me the same error.
