Just a few days ago I get a nasty message on my PC saying my version of CD is pirated

EXCEPT FOR ONE


In X5 I'd often have a drawing split up into layers, and I'd turn off layers I don't want exporting. Never had any issues.
Not so in 2017, I disable printing/exporting on a layer but it still exports that layer (using DXF). Also, unlike X5, I don't get any warning box saying something like, "Visible objects on non printable layers will not be exported". X5 would always give me that message.
I'll get onto Corel about this but just wondering if anyone is the wiser about this problem.
