i don't mean to hijack the post but i have a similar problem. I also bought the audiomidi buy 1 get 2 free, i received the activation codes i tried to register One using the appropriate codes from the email, then i was asked to choose the synth of choice ( i chose Arp2600 since i know it already) - even passed the activation code in my dongle - but all this without any software installed, simply cos i don't how to get it, download it. What am i supposed to do. I wrote a tech support message already. .
