And all my plugins passed!
There was one alert box, forgot about what, but I could just hit [OK] 
Oh yes, thanks for the heads up, let me turn that baby on so it’s ready before the clock changes again
Yeah, phew! I normally work in Artist 7 nowadays and only had to deal with it the actual day the time changed here.
But about a week later I made the mistake of firing up Essential 5 with the intention of grabbing a quick render from a VST effect that Artist won’t scan, and turns out I waited 4ever cause Essential 5 wanted to rescan all my VST’s again. Ugh. Don’t open old versions of Cubase after the time change!!
