Hi Jhighton,
Dear member of SanDisk Community, welcome.
What I would do in this case, because it seems that something is wrong, is following:
1- Make a backup, to your PC, urgent, slowly extracting the contents of My Vault.
2- Then, in another Pendrive, start again with the new version of SecureAccess.
3- Please, see this link, which may help you in something:
Luck.
Regards, Alfred. (Google translated)
