SanDisk Secure Access V3 fails to start

Hi 

I have stored files in the vault on version 3 and successfully accessed twice before today.

When I have tried to open the vault today I cant, I receive a pop message that reads: 

ScanDiskSecureAccess is already running

I have hit task manager there are no processes running,

The vault shows up on the USB window, however the only files that show under the USB drive in the computer menu on the left hand side of screen are the 3 folders:

SanDisk SecureAccess

SanDiskSecureAccess Settings

SanDiskSecureAccess Vault

not the application where all the files are:

SanDiskSecureAccessV3_win

Any ideas on how to get back into the vault?    (it is the same PC that I am trying access from that I used to copy the files across initially)
