Help, I can only save projects on my desktop

Widows 7 64 bit. Cubase 9.0.1 Build 113 (64bit)

I can no longer access my other HDD’s on my pc to save my new projects.
When I select Prompt for project location > Create > Cubase will only allow me to save my project on desktop.

Cubase used to give me the option to select any hard drive on my PC. I currently have 4.

Please advise

Thanks in advance
