You'd be really wise, in my opinion, to get your minting rewards and hold on to them and mint again right now the price looks like its doing well again and who knows where it is going next.
Make sure you upgrade to 0.5.4 of the wallet and resync. Your wallet might be too old if it has been that long. Export your private key and save it in a safe place.
Thanks, for the tip. I'll look into doing that!
