I have json back up file from August last year and want to import to the new client but it complaints about invalid password. I'm pretty sure password is correct. I also tried to copy json file to wallets folder in AppData\Roaming\BitShares\wallets but client seems do not read the file. (It worked for me before until I upgrade to windows 10). Do I need to rename the file ?

Please help me, many thanks.
