Hello, I am on OS X Yosemite with XDN wallet ver 0.99b which I didn't open since about early June of 2015. I tried to sync for the last couple days and my wallet doesn't connect. I tried to upgrade to current wallet, but I am getting "The application “digitalnotewallet” can’t be opened." I tried new wallet on Windows, but I cannot import my OS X wallet since it is asking me for a password and none works. I read the forum and tried to export/import private key, however on my OS X wallet "Show private key" button is greyed out. I do have my darknote.wallet that I backed up in June. Any idea how could I get my old wallet working? Thanks
Try option clicking on the application then select open and confirm in the dialog you want to open it anyway ; a simple security
setting on OSX may prevent you the first time from being able to open apps downloaded from the internet by double clicking .
I am not sure if you would have to use the old software version to be able to see your private key ,
but anyway you would have to get through the password request first to have access to your wallet .
That is likely the reason why your export/import key is greyed out — the wallet remains encrypted .
