Set the FTP program to "anonymous login / connection". (or something equal... not sure what the right translation would be)
In Filezilla it is done like this:
1.) Click on the button below "File" menu.
2.) Put in hash.com at "Server" on the right side.
3.) Put in "Anonymous".
4.) Click on "Connect".
Or the other way:
1.) Put in hash.com to server at the top of the software.
2.) Leave Username and Password empty.
3.) Click on "Connect".
