Thinking of mining ravencoin on my gtx970 windforce OC

Hello, I've recently discovered ravencoin after a friend of a friend told me about it(he is mining the coin). I am fairly new to both crypto and mining so anyone willing to point me in the right direction for starting out?I tried following this: https://www.youtube.com/watch?v=O7KsSS6FA24 but I get this error: "algorithm kawpow not supported on device0". My question is how do I fix the error and if it's worth fixing it to mine on my gpu and where does one sell the coin?
