I have created a dropbox with the file in it that you will need and will send you a message with the link and the login credentials  in it. 
Hi,  I'm trying to download the B.20, A17 firmware for a TL2000 tape drive but the download isn't working, I just get the message "Sorry, the requested file could not be downloaded." Is there an alternative download link available?  Thanks,  Chris.
