Mindfox, or anyone! I need a little help with a problem please - I started a fresh wallet and solo mined 13 blocks. The balance of the wallet is showing as around 11,600 WATER. However, when I tried to send coins I get:

"Error, the transaction was rejected. This might happen if some of your coins were already spent, such as if you used a copy of wallet.dat and coins were spent in the copy but not marked as spent here."

This is a brand new, fresh wallet - not a copy of an old wallet.dat

All the mined blocks are confirmed 200+ times and are showing in the block explorer - however they say "not yet redeemed" - what does this mean? Does this matter?

Here is one of the txids: caf992067db1916c6c4726c2b3ac559a9cee41cd50fae6b178169104eaa74095

Can anyone shed some light on this please and suggest how I can successfully send these coins?
