Error: Exception is thrown in contract code/in contract execution

Generally speaking, "Exception is thrown in contract code" means exactly what it says — something in the contract didn't work correctly. Since this means there's a problem or some dysfunction in the smart contract — an area over which we have no control — we're unable to assist you.

In these cases, please contact the owners of the contract for resolution or advice. The developers should post in our forum and/or on the Ethereum stack exchange to seek help.
