Unable to update Pages
Hi,
I'm trying to update Pages as prompted by the App store but keep receiving the message: This update is not available for this Apple ID either because it was bought by a different user or the item was refunded or cancelled.
It's a new macbook so I've not knowingly refunded or cancelled it and am entering the only apple ID I have. Either way I can't find a way to update or delete the message. Does anybody have any ideas please?
Thanks
MacBook Pro with Retina display, OS X Yosemite (10.10)
