Unable to download fasta files

I received the following message when I try to download fasta files. Any suggestions on how to fix this error?

Thanks,

Message:

ERROR: incorrect number of sequences found.

You requested 1 sequence(s) with the following identifiers:

27069

from the following databases:

natsume.shinsuwase.v1.0.11262014.genome

but we found 0 sequence(s).

Yes. Add a few letters to the sequence ids, so that 27069 becomes ns27069 for example, and recreate the blast databases.
