I am the same as the above two.
Bought the update, selected the PC download from the shop, it lost connection to the server, used my link from email to get back to the download page in the shop and now I am only being offered the Mac download. I got in contact with support who replied with the link in the shop should work (still only Mac offered) or try the ftp.
So tried the FTP, doesnt like the password on two browsers so had to log in annon, to find there is no download for cubase 6.5.
