Start Etherminer........ point it at the gexp-windows............. ip and port.
I have 110m mining atm, gives errors Invalid header on a mined block so nothing added to the wallet etc.
if you want to check your balance ( after you have created a new account) use the following command line in the console.
web3.fromWei(exp.getBalance(exp.coinbase), "expanse")
Will wait for release as no benefit in mining atm.
