Secure Access doesn’t show vault content


I have a sandisk 16gb flash drive. I opened my flash drive after a few months. Now, when I open my sandisksecureaccessv.2-win it is empty and doesn’t show the contents of the vault.

I can see a sandisksecureaccess Vault and it has all the files (occupying 4.5 gb of space). But My Vault shows no files.

Please Kindly help. These files are really important and I have been reading for past 2 hours to find a solution.
