Purchased Mackie CR3-XBT's, registered but don't have 'Musician Collection' Plugins?
 

I have purchased MACKIE CR3-XBT speakers that come with Pro Tools First and a 'Musician Collection' set of plug ins.

I used the link provided (avid.com/pro-tools-first-mackie)

As I had an existing account used the sign in option and entered the serial number of the product along with my login. I was sent to my account page but can see nowhere to download/redeem the 'Musician Collection' set of plugins.

Full details of the offer here (https://mackie.com/blog/mackie-partners-pro-tools-first)

There is an AVID support case for this: 04162719

What should I do?
