another problem?

Er.... don't think the Hudl2 is a Windows device. Always thought it was Android, probably Lollipop by now.

Advice from Tesco is here:

Unfortunately that seems to be what you have done: clear cache and do Manage Space, Clear All Data.

This sounds a bit more promising: it is to do with the Google Play app in the Lollipop update already being outdated:
