Hi all, I’m in a similar boat.
I have a DVD ROM of LE4 in front of me but with no drive onboard my new laptop…
@Martin.Jirsak - you seem to be resident champion here. May I ask if you have links for Cubase LE4 and Cubase AI4?
I have licences for both by cannot find the LE4 download on the site anywhere, and cant install AI4 without an existing version of LE installed… 
Any help would be much appreciated.
