GeForce GTX 970 / WIN10

I'm using now QtMiner from ethermine.org
My .bat file: qtminer.exe -s eu1.ethermine.org:4444 -u 7c9dd56bf5d842246efecdf4af6c9d0bbe5d66d8.rig1 -G

but 3 days ago QtMiner get error "QtMiner.exe has stopped working".

Please, can you help me how to using Claymore with my Ethereum wallet 7c9dd56bf5d842246efecdf4af6c9d0bbe5d66d8

Thanks!
