Question from a newbie that is learning it's way around the blockchain world. Hope you can help me out!
My Ethereum Wallet holds the main account and some accounts for testing. I also made one Wallet Contract with the main account as owner. Several months ago I transferred 1 Ether from the main account to the contract without problems.
I have tried several times to transfer the Ether back to the main contract but keep getting an "unknown account" error after providing the password and selecting Send Transaction. There is no entry in the node log so I have no idea what is happening here. Both the contract address and the main account address are filled in by the program. I have tried manual copy-paste, but with the same result.
Does it have anything to do with the status of the blockchain download? I have kept Wallet running for a whole day now, but there are still more then 400k blocks left to download.
