Hi,
It seems that since my PC updated to a newer version of Bitdefender (following the update from Windows 8 (Pro 64bit, English) to Windows 10), I've been unable to open the BVD file I created in the earlier version of Bitdefender. The BVD file was created under an earlier version of Bitdefender Total Security 2015 (originally purchased ~ August 2014), but at some point since, the version of Bitdefender I'm now running no longer accepts the password (I didn't test the vault regularly, but I know it worked for some time after creating the vault).
As Bitdefender was acting up on my PC (on which I created the vault), I tried opening the file from another Windows 10 PC which also had Bitdefender installed, but on that PC, Bitdefender reports that the file is not a valid BVD file. Later, after some troubleshooting on the original PC and reinstalling the current version of Bitdefender, it now reports that the password is invalid (which I know is incorrect, as it has been stored in a password vault and has not been modified there since).
I've seen previous threads where people were only able to get their data back by restoring their PC back to the original Bitdefender version (http://forum.bitdefender.com/index.php?showtopic=38948). Would it be possible to get an offline installer for the version of Bitdefender that would have been current in 2014? I'll happily reinstall W7 over my current OS partition if it will help get my data back, but I suspect I'll need the same version of BD I had at the time. (The BVD file is on a secondary partition which helps).
Does anyone have any other suggestions? The BVD file is ~ 30Gb and I really don't want to loose it.
