'Invalid Parent Path in Archive' Plss HELP!

I have a SanDisk Ultra Fit CZ-43 128 GB USB 3.0 Flash Drive which came with the  SanDiskSecureAccessV3 software for MAC. I have a 110GB of my entire life’s work and portfolio locked into the drive. My password hasn’t changed but now when i type it in, it gives me this error ‘Invalid Parent Path in Archive’ .  I tried copying both the vault and the v3 to my applications folder on my 15" 2013 Macbookpro running MacOS Sierra 10.12.5 and when i run it off my mac it gives me this error:  ‘This application only runs on a SanDisk flash drive’.  I desperately need access to my drive. Please HELP. 

Hi, are you still interested in recovering your data or you got rid of your Vault and/or USB Stick?

I can help you save it if you are still interested in recovering your data.
