why does I want to send the coin to the livecoin exchang wallet address,my wallet also point out that
"MaxIn count is too big",how to solve it???


Maybe you was mining solo, just change anonimity level to zero and send again.
DO NOT FORGET TO INCLUDE PAYMENT ID you got from the Livecoin exchange. Transaction without won't be credited to your account.
Upd. just saw the pictures. Try to reset your wallet to get rid of unconfirmed coins if they are staying for long time. (Prior to do anything make sure you have backup of your wallet and keys)
Unconfirmed amount is change from previous sent transaction if you haven't receive that amount from elsewhere.
P.P.S. Judging from the dust after dot in your balance you was mining solo, therefore sending with anonimity zero will help and transaction will pass.
