So, you're connected to a node. By clicking on “View” and then on “Addresses” you should be able to view your address(es). As far as I can see from the History tab, there are no transactions with the addresses you've generated.

Yes i think written the private key wrongly
i remember i take the copy of these keys in fast way - how ?
I copied the numbers and letters on top of each other - the number of lines became six, but the sixth is a number of eight letters and numbers - I think it is checksum
all together = 256 latters and numbers capital letter
We must make sure of the previous procedures, whether they are the same procedures or not ?
When I bought the coin, it was from a website bitcoin - but i am not sure about .com or .org
