Recover my SuperVault files
First, try to decrypt the encrypted vault on your PC/Mac using other encryption software (presuming, you've its password &amp; encryption key). The encrypted vaults are generally universally compatible, but not necessarily.

If it doesn't work for you, setup an Android Emulator (virtual Android phone) using Android SDK. Enable Android Market in it. Install SuperVault &amp; Dropbox using Market. Use Dropbox to download vault file in its virtual sdcard. Decrypt files &amp; withdraw them using Dropbox.
