I purchased the HD Blu-Ray plugin for my Toast 11 installation after purchasing a Blu-Ray Burner. I had considerable trouble with Toast 11 running on Sierra; it continually crashed and I wasn't even able to get to the point where I could try burning the disc.
I decided to upgrade to Toast 15; do I need to purchase the plug-in again? I noticed that when installing it for Toast 15, it says Toast 11 during the installation.
I have a late 2015 21" iMac, with 16Gb of RAM.
