Drive unlock impossible after update

I use a 4TB USB WD My Book with encryption on a Mac High Sierra OS. After updating the WD Security app the drive unlock app no longer accepts the passphrase and the drive cannot be decrypted. I can’t seem to find older versions of the apps in order to uninstall. Any advice?

Hi d2000,

Maybe you should try contacting WD’s Technical Support about this.
