Data in the vault seems to have disappeared

I have successfully loaded about 44 GB data into the vault. When I now try to open the vault all references to the loaded data files have disappeared.  However, when I check the PROPERTIES of the drive it shows that 44 GB of used space and  72 GB of free space.

How can I get my data files to show up again ?
