I have a unique problem in that my events website developed some kind of problem in Pro X (the last one before the subscription thing) but I found it opened alright in Pro X11, which is where it started it's life. So currently I run both versions to cover that and all my other work. So I'm forever opening both. And both put up nagging messages but even if I click the do not show box it all gets cancelled out and up they pop again next time I open the alternative version.
