Sorry for the misunderstanding... It wont allow me to continue with the main quest, it continues to prompt me to continue the Brothers in arms - velen mission. Even if I try to to continue on with the Isle of Mists mission there is no yellow dot indicating the start point for the Isle of Mists mission. I hope this makes my situation more clear, thank you for your responses.

Thanks for the heads up, but she is not in her hut... although I havent tried Fyke Island, I shall try that next... thank you.
