At least once a month, sometimes more often, Cubase loses all it’s preferences. This is so frustrating, fortunately, I back them up daily (automatically) but why does this happen?
Doesnt happen here… so its not a normal thing
I did notice that the recent projects folder was empty after demoing rnd and open deck plugins though…
Try upgrading to 7.5.20 and see how it goes…
=)
Never had this issue but i would advise upgrading to 7.5.20 it’s very stable indeed 
Just happened again yesterday, does this happen to anyone else? I’d love to track down the reason.
Has just started happening to me with 7.5.20 but I think it is related to a UR28M crash
