These are the original Excel files used to create the building and unit production text files. I've uploaded these because opening the .txt files that come with the game in Excel and then saving out the files again produces errors that stop the game working. They were created in Excel 2000, so they probably won't load into earlier versions of Excel.
In order to create new building and unit files that can be recognised by the game, save out the excel file as a TAB-DELIMITED text file. The option to do this is in the "Save As" dialog box in Excel. From the "Save As Type" dropdown list, choose the tab-delimited text option and then save.
Don't forget to make backups of your existing crusader_build_prod13.txt and crusaders_unit_prod11.txt files before you overwrite them with new ones.
