Hello! I have some AERM obtained from minig that can't be balanced on my desktop wallet, probably due to the error occurred on the blockchain.

In "Transaction" window it says "Generated but not accepted. Obtained from mining" and furthermore in tranction details it says "Generated coins must mature 510 blocks before they can be spent. When you generated this block, it was broadcast to the network to be added to the block chain. If it fails to get into the chain, its state will change to "not accepted" and it won't be spendable. This may occasionally happen if another node generates a block within a few seconds of yours."

So, what can I do to not lose these coins?

Thank you all
