NOW TV with AVG

Im trying to cast NOW TV to the TV using Chromecast which works ok until I try to play a video. On clicking tp play a black box appears on the TV screen as though it's going to load but never does. The Lap top continues working ok and plays the video but it doesnt cast.
I'm using an ACER lap top running Windows 8.1. I had previously used NOW TV before without issue as far as I'm aware it is only since purchasing AVG internet security that this has occurred.

Any help would be appreciated.

Thanks
