If that pin (which pushes back the unhooking slide) is in fact not pushing in, it could be due to the gun needing cleaning. But I would find it hard to believe that it would be that dirty though.

That pin should be able to be pushed in by hand with the forend off.

The link that Robin posted should explain that the ejectors need to be cocked in order for the forend to be installed. If the ejectors are cocked, pushing the cocking slide pin to the flush position while installing the forend should be a piece of cake. It is time for the original poster to bring us up to date.
