I've had a look at the Mount and Blade Warband files in My Documents. There are two folders Mount and Blade Warband and Mount and Blade Warband Savegames. In the Mount and Blade Warband file there are two further articles, SceneObj and rgl_config, which was on Notepad. In Mount and Blade Warband Savegames there is a file called Native, which then contains two further articles, sg00.sav and last_savegame_backup.sav. When I click on these files, a notice saying that "Windows cannot open this file" appears.
After looking at rgl_config, I realised that information may be helpful to anyone who might want to solve this problem, so I've copied it here:
