the files in the vault folder are teh encrypted database files. these are not readable. you have to open the SecureAccess application to view the files. If the files are not seen inside the application it seems the database is encrypted. If this is the case the files would not be recoverable. you would need to format the drive and start over.
not sure what you are referring to unless you are talking about the message that tells you how to use the app. should be able to say ok to that and access the vault. if you dont see the files in there it is possible the data base is corrupt. if you delete the application the files are also deleted. encrypted files can’t be recovered. if you do not need password protection and encryption just delete teh secureaccess and vault files and use the drive as a normal storage device.
