ZIP Error(0): Status(0):

I'm attempting to change the Accounts billing country field from text to dropdown.  I found a manifest and custom code php online.  When I click Upload in Module Loader, I get this error:  ZIP Error(0): Status(0): Arhive(upload://change_account_country_to_dropdown.zip): Directory(/tmp/q8hT83)

I hate to ask a newbie question, but I cannot find a resolution in any research.  Any help would be most appreciated.
