hello there.
i email my wallet file and pass to fix my problem.
but still now just no answer ( from January 11, 2018)
plz answer me.
thanks

I can help you on monday!

I don't know the specifics but there is some way to fix this by basically rebuilding your wallet.  The incomplete transaction takes some time to expire (a day or two) and then if you just run some command like rescanning your wallet, it will clear the stuck transaction.  I think you might also need to download a new blockchain.

Again, sorry I don't have more specific help, because I can't be sure it works with this coin.  With another CryptoNote coin, I deleted my blockchain, reverted to an old wallet file (or you can try to re-create the wallet from the seed or private key).  This means the wallet has to get all it info from a new blockchain, not what's stored in the wallet (and the blockchain won't have the stuck transaction, because it never happened on the newly-downloaded blockchain.  Your old blockchain file may still have the stuck transaction attempt).
