I use Toast Titanium 10 to burn my photo images to a DVD. Since upgrading to El Capitan I am getting error codes (Sense key: medium error and Sense key: illegal request, Sense code: write error. The disk is burned but is not verified. I have tried to see if there is an upgrade for this version of Toast but when I look to see what version Iim running I get no info (blank window) Any ideas on what the problem could be?
