what blockheight is it now ? atm I see atleast 2 different invalid chains at heights 2479 and 2962. Looks a bit like a forked blockchain to me. Tho it could be some obsolete chains ghosting around while im at initial DL.
EDIT: from debug.log -> "receive version message: version 70001, blocks=4407" hmm....
Your client probably just got stuck on block 2479 or 2962 while downloading the blockchain.
Start the client without mining and wait for the entire blockchain to download before starting the mining process.
you can see what block the real blockchain is at here:
