Bob, Chuck, Bristol_Jonesy, and others.
OK, here is the current status of my SPLAT install. I laid low all this time since my last post, and private message exchange with Bob. Then, yesterday I had notification to say SPLAT was updated, so I used CC and downloaded and installed the 'latest' update 2016.11 (22.11.0.111) and then clicked on the launch button in CC and held my breath.
Lo and Behold! Platinum fired up JUST FINE and I was able to actually open one of my earlier projects and run the file!! Mind boggling! I don't know what happened, but it appears the folks at SONAR did something after all, right? Kudos to them!
Grateful thanks to ALL of you who helped, especially the folks mentioned above. Now, let's make some music!
