I want to mine ether. Trouble with eth miner

JezzaJezza Member Posts: 6
I want to mine ether on windows 10. I have downloaded Ethereum 9. I have geth and ethminer. I open cmd and type C:\>geth --rpc. This syncs to block chain. Then I type C:\Program Files\Ethereum 0.9.41\Release>ethminer -G. At this point ethminer starts to mine but then stops and says the DAG can't be allocated in a single chunk. But that only last a second or two then it starts to mine again. It mines for a few more seconds then just stops. I can restart the miner and it mines for a while gives me the DAG error then starts again then stops. Can someone help me

    Fatal: blockchain db err: leveldb/storage: corrupted or incomplete CURRENT file
    So I cpu mined a while just to try it out and play around and at some point this error showed up

    i am actually getting this error when I try to run geth. From CMD prompt I type C:/geth --rpc
    that was syncing. I waited 4 days for it to sync before I attempted to mine. It WAS synced at one point. I'm not sure how to get my node back.
