It seems I am stucked mining since 8 of October, as no new transactions arise. However, CPUs are working. I was on 1.4.9 version since it was delivered, and I have updated this morning to 1.5.0, but I am still in the same situation. Getinfo and getmininginfo show correct data. What could be happening?

PS. Traditional wallet/miner, I am not talking about the new miner.
