Anybody else getting this after the update on Steam? Can't load my save.

Maybe this is a little late but i got a fix (for everyone who is still reading this).

Just use the automatically created Backup Saves and paste them into BatmanAK if u got the "newer version" error. They will work :) (even if they are the same)

@jtmosh: What console / system are you playing the game on?

@fullmetaljack: I just fixed this using FullMetalJack's method, placing the backups into the folder the game loads from.

I also had to delete all the save data from all other locations AK stored any saves or backups.
