SecureAccess 3.0 not working on Mac/El Capitan

Hi All,

I’ve upgraded to Mac/El Capitan, now I’m having a problem with SanDiskCruzer Glide 128gb a dialogue box pops up when I launch  SanDiskSecureAccessV2_mac " This version of SanDiskSecureAccessV2 requires a San Disk USB Flash Drive. Please insert one & try again". It was fine before the upgrade.

I really hope I can retrieve the data as it is a lot of precious photos of family who have passed away.

Any ideas folks ???

Thank You.
