Can't re-add VM

[deepphil]

I had one VM with one snapshot. It was located in /Users/username/Library/VirtualBox/Machines. I used the Machine -> Remove... command, but now I want to add it again, but VirtualBox won't display the /Users/username/Library/ folder when I use the Machine -> Add... command!

How do I get it back?

(Btw, I can't clone it because I don't have enough disk space! I'm happy to move it though...if I can find out how to do it.)

I'm using Vn 4.2.2.
