Do your private keys begin with a '5', 'K', or 'L'?
If it begins with a '5', is the private key 51 characters long?
If it begins with a 'K' or 'L', is the private key 52 character long?
If none of the above, then you don't have a valid private key.
Yes I am fine with that numbers are correct....
its something to do with wif format?
