New windows 10 installation, after a very long time

Setup : Scope samplerate 48kHz and running Cubase.
Cubase is using ASIO.
When I export wav data, for example : sequence from vst instrument and then i open that wav with Soundforge, I can't play that wav, cause program writes me that "device is not available".
I mean I can play that wav in Soundforge using 48kHz, but I must close Cubase and select ASIO for Soundforge.
While i'm working with my project it's time consuming for every single wav , closing Cubase and run Soundforge.
Then, changing samplerate to 44kHz , I can play that wav normally. (Cubase - ASIO + Soundforge - Wave)
Do you think for Cubase + Vst instruments is 44kHz enough or 48kHz gives me better sound control ?
The problem is, that I didn't re-install windows for a long time and I think that everything was working also with 48kHz and running everything together (Cubase, Soundforge... ) I really can't tell 100%, but i'm using 48kHz setup for a long time.

I hope it's understandable.
