Playback and LV problems

Hi guys and girls,

So I haven't used my d3300 for a couple of weeks. I've just switched it on and I've got the messages ''Playback not currently available'' when I attempt to look at my photos and ''Cannot use live view at current settings or under current conditions'' when I try using live view. I've had a search of the net before posting but I can't find any reason or solution to the problem. I'm not using the wireless adapter, I've reset shooting conditions and camera settings and I've also formatted the SD card/ tried using a different 1 but to no avail.. Can someone please help!

Some time my D3300 gives random messages, if the lens is not seated properly. Try detaching the lens and reattaching it a few times.

If nothing works take it to the nearest Nikon service centre, there may be a problem with the body.
