I got the same error message.
Looking in the wallets folder, a new default folder was created.....there was nothing in it and nothing in the default-DoNotUse folder.
I'm sorry about this cube, thank you so much for your time. Would there be any point in uninstalling 0.9.3 and running an older version of the Windows client....one that will accept the backup file?
The default folder is the wallet folder. Rename it to 'default-DoNotUse' and when you start up the client, it will create a new empty 'default folder' (an empty wallet). With an empty 'default' wallet, hopefully you can restore the backup. bts0.9.3 is compatible with bts0.9.1 wallet. There is no need to uninstall it and install an older version.
This may turn out to be a tedious process. Another easier approach you may consider is using the full professional wallet recovery service from xeroc.
If you think we've reached the end of what we can do via your remote help, i will certainly consider it. How does one engage with Xeroc's professional service? Via forum pm?
Before I do, one last thing......I can handle tedious, i just don't like using up your time!. That said. May we please have one last attempt to get me to do what is needed?
So to be absolutely clear.......
I turn on the laptop,
navigate to C:/Users/Ben Mason/AppData/Roaming/BitShares\Wallets\default
rename to C:/Users/Ben Mason/AppData/Roaming/BitShares\Wallets\default-DoNotUse
Then run the 0.9.3 bitshares client
Once it gets to the login screen, select import wallet...replace existing wallet.....type in password
If the above is correct and I get the same error message, what should I try after that? Is there anything else or is it at this point I need Xeroc?
