I for my part can very much recommend Cubase. Before I bought it, I had asked around and many of my friends told me that it is too complicated. But since I use Yamaha devices, I figured I’ll give it a try anyways and I am very happy with it. It takes a little while to get the hang of it - but it is definitely worth it.
As for the dongle: I am no licensing expert, but I believe you will need to buy 1 dongle from Steinberg and after that you can load/register several Steinberg software packages on that stick. I also believe that this is a special stick where you can’t just use any other flash drive - but maybe I am wrong. I just bought mine from Steinberg and it has been working for a long time without any problems.
No worries about the English part - you’re doing fine and I can understand you well
If I remember correctly - you will need the dongle to activate it. Folks please correct me if I am wrong
How about this idea: To start today - just use an evaluation version for the time being and then ask your aunt to maybe send the dongle ahead of time in a padded envelope so you have it before December. Just a thought.
You can then download the Cubase 6 / HALion 4 licenses to that dongle by entering the activation codes supplied with your package which will make you eligible for the grace period to Cubase 7 / HALion 5.
