There's a problem with this add-on, mainly in the Oob files.
Please check:
Scenarios Baylen, Albuera and Salamanca are ok.
Maida and Vimeiro have a separate (not in the Army folder) OoBs folder, when the destination folder is OoB. If the folder is extracted as is, it will not be read.
Talavera has a separate OdB folder (destination folder is OoB). Again, only the enclosed file should be extracted to the OoB folder.
