Seeing the start of the XML file would be very helpful.  And if is
empty, what has been written to the error handle?  I would guess maybe
the database is in a new location or something simple like that...

print error_info.read()

Another thing to check is the version of Biopython on the new machine.
 Earlier versions would default to asking blast for plain text output
instead of XML.
