Install problem

[soupman]

Hello.  I am getting the following error when attempting an FTP install
from a Windows machine:

Cannot parse information file for the bin distribution: I/O error. Please
verify that your media is valid and try again.

I tried removing the file and this error still occurs.  The FTP server
logs on the windows machine show the freebsd box is able to find and
request the file, but it seems not to want to use it!  Anyone have any
ideas?  Thanks for your help.
