This has been mentioned before but I can't seem to get the right keywords to find it with the SEARCH engine.
 
Basically, following the link in my invitation-only email, I get a price of $525.00 in my shopping cart instead of the upgrade price.  There was a workaround for this issue posted in a reply but I can't remember what it was and I can't locate the thread.
 
Anyone remember it?

Does your account have your previous purchases listed? I have seen reports where missing products cause this problem.

That seems to be the case with me as well.  What's been the remedy for this?

Here is the FAQ http://forum.cakewalk.com/FindPost/3148924

The issue was with the email address in my new SSO account.  I changed it to my old email address and my previous products showed up.

Now the proper price is showing up in the invitation-only pre-sale page.
 

That seems to be a common problem.
Glad it was that simple.

What is the proper price? Is it $150? I did not know we need invitation for that. I never got any invitation e-mail- does it mean- I will not get upgrade price? I thought I will just go and order.

The upgrade from X3 to Platinum is $149.00.  That is the normal price from Cakewalk.  I was speaking of the invitation price showing up as the full price for SONAR because my previous purchase of X3 was not showing up due to my change of email addresses.  
 
I didn't get a pre-purchase invitation until today.  You still may get one as this seems to be a way to have a soft rollout of the product in order to work the kinks out of the new e-store and the Command Center.
