Was a solution ever found for this? The replies to the post, didn’t answer his questions at all. I had the exact same situation copying files and getting signed out, and now when I sign back in all files are missing (not just the files that I was copying) However, all of the .dat files are still in the SanDiskSecureAccess Vault folder. But after logging in to SanDiskSecureAccessV2_win there is nothing. Is there anyway to access the files now?
