Hi there and help for a Newbie

Hi folks, having fun getting to grips with it all but have a problem.
I have an IPad2 has been working great. I have Keynote for presentations and had an update for it and a couple of others, tried to update and said not compatible with this iPad. I downloaded IOS 5 and also an ITunes update but still will not working. Why, can anyone help? Also had tried on Safari a couple of things last night but kept getting the same message.:(

It might be worth rebooting the iPad to see if that clears the problem. Press and hold the Power and Home buttons until the white Apple logo appears - it can take a while - and the iPad will reboot. That takes a while too.

Get back to us if the problem persists.
