Mined 2K coins, restarted client, and it was all of a sudden 4000 blocks behind, and balance 500 coins, and not syncing, is the block chain forked / f**ked? (I do realise this was just a test / wasted effort! just wondering whats up!?)
my address is SFNcmSMm4hz1GjEgWUzRhYsQEkJNn41QtA, and client is the pre-compiled windows binary (v0.6.3.0-g6261cf7-beta) is there any block explorer?
Looks like you mined it on your own, splitted from the rest of the network. Likely you did not have any connection to other peers.
When you restarted your client your chain was smaller than other one, thus you were 4000 blocks behind.
