Ok and whats the step ive missed before?
I feel i did allright using openssl command.
You also need to do a bunch of stuff with the wallet-tool in order get the data from the protobuf to a key. Those are near the bottom of the file under the headings Recovering from protobuf wallet format and Recovering from Base58 key format.
Please be more clear, also since you are respected user i can pass you my file.
I suppose you can do that if you think I am trustworthy. If you want to do that, send me a pm and I will send you my email.
