Riaz,
That is very strange. If none are accepting the enter key, then I am not sure what else to do. I am sure you tried turning the unit off waiting for some time and turning it on and trying to hit enter from there.
Other than that, I am not sure what else to do. Let me think on it for some bit and let you know if I come up with anything.
