Cubase Artist 6 ONLINE UPGRADE for Cubase Essential 5 Users

Hi, I would love to upgrade my Cubase Essential 5 to Cubase Artist 6 but is very, very difficult to make an upgrade here in Brazil… I tried to buy in others countries but they don’t send (ships) to Brazil… unfortunately …

Could be great to have an online upgrade like the Cubase Essential 5 option !

Please Steinberg !
