Must be response in console on command refresh? I got nothing.
I recall seeing that error when testing an early release of MoneroClient.net, I think its caused by one of two things:
(a) entering the wrong wallet password
or
(b) Using an imported wallet.bin file from a different version of simplewallet, either different release or from different OS
Looking at some notes I have I see that error quite often, but it is usually followed by the wallet then loading ok, so I suspect its not related to your problem. Entering the "refresh" command should make simplewallet scan the new blocks in the blockchain for any txes which belong to your wallet address - if you are expecting to see more coins received/sent but that's not happening then I suspect the problem is actually with your bitmonerod
