I upgraded to Platinum yesterday.
 
I started the download on Command Center and when I checked this morning, it had stopped with an error.
 
I restarted and it spun up to where it left off (probably timed out) at about 50%.
 
As you can see, my internet is very slow, as I live in the very rural CNY.
 
I am in the office now (fast internet, in the city) and went to my products page or "My Account" and downloaded all the files there.
 
Can someone post a link on what my next steps are to upgrade offline, thanks.
 
I currently have X3e and no NOTHING about XLN Addictive Drums (I think I am supposed to select 2 or 3 different sets or something).
 
Much appreciated, thanks.

If you leave X3 Producer installed, the packages needed for Platinum are

• SONAR Platinum
• SONAR Help and Tutorials (if you want the local help or Reference Guide pdf)
• Anderton Collection
• Boz Digital Labs ProChannel Collection

You will need to get SONAR authorized, see the section on activating SONAR http://www.cakewalk.com/Documentation?product=SONAR&language=3&help=Introduction.28.html. Here is a video about the process https://youtu.be/roIgly_GjoI
 
Addictive Drums 2 must be installed directly on the machine using the XLN installer and an internet connection.

I have the files loaded on an external HD.
 
I will place these files in the folder in CCC on the PC I use for the studio.
 
The only reason it did not work for me is SLOW speeds.
 
Once I place the files in the folder in CCC I should be able to finish this without and offline activation, but if not, your post is VERY helpful, thanks.
