Cubase LE5 to LE6

Hello I’ve bought an Alesis iO2/Express which is deliver with Cubase LE5 but when I want to activate it, the website said that I need to upgrade my version. In the section download :

I find Cubase LE 6 to LE 6.0.7 but there isn’t any upgrade for Cubase LE5 to LE 6.
Please help me !

Hi and welcome,

Did it ask for upgrade of Cubase LE? I would expect, it asked for update of eLicenser Control Center. Or am I wrong?
