Re: [ANN] Slimcoin : Proof of Burn NEW BLOCK GEN, Mineable by low power computer!
make sure that your wallet is properly synced, currently @ block 12225
I think that might currently be a problem for many 
Mine repeatedly gets stuck at 10202, with the debug.log citing "ERROR: ConnectInputs() : tried to spend coinbase/coinstake at depth 408". I've got it wiping everything restarting periodically, but might as well wait for an updated wallet with a proper fix
