If you use Windows XP the savegame will my kept in My Documents-->My Games-->Civ4. When you click 'post reply' to this topic there is a subheading called Additional Options where you should click Manage Attachments. Click browse, find the save you want to upload in the method I described then upload and we should be able to see it.
That said I'm not sure I trust you enough to help further


The fun for me is learning without asking
