Got new chain you posted. The transaction is still in the wallet as conflicted.
Will wait for a fix.
Seems like you were trying to spend coins from a previous transactions output.
Turn on coin control in the send coins options, it will show you what is available to spend.
Looks like your transaction gave an output of OP_DUP OP_HASH160
