Lost all files and failed update to version 3?

Help! I have the Scan Disk. cruzer glide 16 GB. It was full of photos. Now, when I try to log in it shows only files related to an update to version 3 (?). If I try to update to version 3 it fails everytime.  

Are my files gone? What kind of craziness is this? Thanks!

If your files were not stored in the SecureAccess vault you may be able to save some of them using a free recovery app from the list I posted here:  http://forums.sandisk.com/t5/All-SanDisk-USB-Flash-Drives/Download-new-version-lost-access-to-all-data-Please-Help/m-p/301789#M5953

If your files were stored in the SecureAccess vault they are probably lost at this point.
