Visual Composer License Renewal...?

I’ve seen some chatter online about the Visual Composer and related issues. Mine is that, when I try to activate the license (which I never had to do until now, & I’ve owned the theme for over a year), I get an “Invalid license key. Please check information in your envato profile.” error. I’ve copied/pasted several times, but no such luck. Anybody else having issues like this?

If VC came bundled in the theme then only the author of the theme can update it and should release a new copy of the theme using the latest version of VC included

Thanks for the reply! Looking into that now.
