Does anyone have a good link or tutorial on how to do the manual claim for the final olympic rewards? I have two keys I need to claim. I got one key to upgrade but I can't send any transactions from it. Says the address does not exist on the chain. My other one I have been unable to upgrade since it was a really old key. I can never get it to unlock during the upgrade process. Any help would be appreciated. The deadline is November 30. Thanks again.
