Monero MRO wallets and mining problems

[danonthehill]

Been mining this all morning with the easy miner, but my computer crashed, opening up the miner it generated a new address, are those coins now lost?

Also bought some on the exchange want to transfer them to my wallet and then on to another exchange.  How do I use the windows wallet?

Actually just noticed the pool I was mining on says it has never found a block, so, I guess there were no coins anyway, still need to figure out the wallet though.
