Kudos to you for getting X2 :) I did as well yesterday.
So in your CW Store account you should see: -
DSF Symphonic
Dimension Pro 1.5
Rapture 1.22
Sonar X2 Producer
along with serials and registration numbers.
DSF you can download and use it now.
DimPro and Rapture are inside the Sonar X2 download - if like me you already see the Download, don't bother trying now.
In fact I emailed support asking like, "Didn't you guys say end of Sept? Why do I already have the Download link?" and they replied immediately saying that we will receive a notification when the download is actually available.
So yeah, pretty much like CJaysMusic said - just sit and wait. :)
Hope this answers your question,
Sam
