Please Help, I've just gotten a new PC and although I imported all files, folders & saves over to the new machine it didn't keep my progress in Napoleon's Campaigns or the Battles. I tried Googling a solution but best I found was someone claiming that progress is saved on Registry Keys & I'd have to edit that. I was always told messing with Registry could brick your machine.
On Steam forums someone kindly suggested regaining access to Campaigns by simply starting then exiting them & I'll try that tonight but that won't solve Battles progress because I'd still lose the little Eagle icons with the silver, bronze or gold status I had before. I'm not as good as I used to be at the game to score as great as I did before.
I actually cut & pasted the Entire 'Napoleon' folder from my old PC into %appdata%. It gives me everything (savegames, replays, settings etc) back except progress in the Campaign & Battles menus. Check out the following link where the resolution was to mess with Registry Keys:-https://forums.totalwar.com/discussion/54831/historical-battles-save-backup
Although I'm hoping for a safer way.
