Generated coins must mature 50 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.

I am having the same problem for 3 weeks now. I have 250k reddcoins and received red in the past, but now I got 6 of these comments in a row, date after date. Is there already a solution?
