Help - Can't restore saved rogue games

[utzoo!decvax!microsof!uw-beaver!teltone!stan]

This is a second call for help; a previous posting to net.games.rogue
produced no response.

The trouble is, we can save rogue games but not restore them.  We
always get the message:
	Sorry, saved game is not in the same file.
when we try to restore a game with "rogue -r" or "rogue save_file_name".

The exact message of the 'v' command in rogue is:
	Rogue version 4.22. (mctesq was here)

Is it hopeless?  Or is there something we can do?
Any aid/suggestions/sympathy would be greatly appreciated.

Is it possible for someone to send us rogue source?
