When I did the latest update, I opened TH3 to check it out. When I opened it on my next session, everything was grayed out, and required to run in demo mode. After 15 days, everything grayed out again?? I sent an inquiry to Cake on 4/28, but still no reply.
Yesterday I rolled the Boutique update back, and re updated, same thing, all components of TH3 grayed out. Ran in demo mode again.
Any suggestions??

Check which release of SONAR is running. TH3 Cakewalk requires 2016.04 or newer.

Just to clarify, yes I am running the latest release of Platinum. That's when TH3 was installed. I updated all. Ran fine initially, but second time I loaded, all the components were grayed out. Had to run in 15 day demo mode.

Are you sure every single thing is greyed out. TH3 Cakewalk edition greys out the components that are only part of the full edition unless you are running the 15 day demo. 

Yes, I realize a few components are not available in the Sonar version, but none are available, and when I try to load a preset, it prompts me to register.
