I did a small acoustic track to try the drum replacer but when I go to region fx>drum replacer it tells me that Drum Replacer can't be used in earlier versions of Sonar, please upgrade to Platinum.  I have Platinum.  Anyone else run into this?
 
SOLUTION: I wasn't running Everett update 1 apparently.  I d/l'd it from my user account area at Cakewalk and installed.  All good now.  Fwiw, my command center had all green dots by all my Sonar stuff so I thought I was up to date...

It may be specifically linked to Everett release and above. Do you have the latest platinum patch installed?

As far as I know, all my sonar bullets Are green in control center

Maybe try running the Everett installer again, and don't forget there was a mid month update. An Everett.1 if you like.

U have to run DR do down at the bottom of list
