This is a known bug in gnuchess.  We have a fix, which will be included
in patchlevel 71.

When you load a saved game, at the end of the game xboard is still in "Load
Game" mode.  If you want to add more moves to the end of the game, you have to
select either Edit Game, Machine White, or Machine Black.  (If you want to
make the first move, you have to select Edit Game, make your move, and then
select Machine White or Machine Black.)  This is rather non-obvious, and I may
change it.

If this is not what happened to you, please provide more details.  Follow
these instructions on reporting bugs, from the gnu.chess FAQ:

Any time you want to report a possible bug in GNU Chess or XBoard, we need to
know exactly what you did, and exactly what error (or other) messages you got.
Run the Unix "script" program, do whatever is necessary to reproduce the
problem, type "exit" to the shell, and mail us the resulting typescript file.
If you're using XBoard, run it with the -debug flag.  We also need to know
what hardware/operating system combination you are using; include this
information in your message.
