I think it's a 3rd party plugin issue, when the project is open in Sonar Platinum and I click on the Toontrack EZMix plugin on a track, it freezes the project. Then I have to close Sonar Platinum. EZ Drummer when open has a wired blue and white key icon at the bottom of the screen. Yet EZKeys works fine. I'm going to create a new project and recording audio and see if it works. I'll throw some of the usually plugins i use and see if it works. By the way I've already uninstalled Sonar Platinum and restarted my PC a couple of times to see if that would fix it, no luck chuck.

Side note: it works fine on my PC at the studio that's running Win10, my Win7 laptop is giving me the problem
