4.2 Update stole my videos

[royal hussar]

Hit the update promt on Sunday and have discovered all my videos have gone walk about. Not one remains have File Explorer and checked everywhere, anyone else experience this ? Music is all there and photos etc but yes same prob with auto brightness and that damn crap clock. Anyway only had my N 7 16gb for a week or so when the 32gb became available in the shops so the Retailer agreed to upgrade me to 32 gb at no cost. Will pick it up this evening and see how difficult it is to recover my books and apps.:-\
