Cant erase saved armies? Got a list the size of a chinese phonebook?
(Looks at Celtic) Well untill a patch comes out to fix it you can easily do it yourself.
Go here for XP: MyComputer/LocalDisk/Documents and settings/Application Data/The Creative Assembly/Empire/Army_setups
Or here for Vista: Computer/Local Disk/Users/AppData/Roaming/The Creative Assembly/Empire/Army_setups
Open the Army_setups file and delete to your hearts content.
FYI: Application Data maybe a hidden file on Vista. If so you may have to do this to see your hidden folders:
Go to Start, then computer
Go to Tools
Choose "Folder Options"
Go to the View tab
Find the tab for "Hidden Files and Folders"
Choose "Show Hidden Files and Folders"
Click Apply and Ok
That will show all your hidden folders.
