I was able to locate 'main.wallet', 'main.wallet.address.txt' and 'main.wallet.keys' but couldn't find the other two
So it looks like you have your wallet, but don't have the airdrop keys. Once you launched cyto-console-wallet and created the wallet, did you run the new_genesis_airdrop_address command followed by exit (from within the cyto-console-wallet program)? (Worst case you will just have to generate a new airdrop address and give it to me and I replace your old address with the new one.)
