Failed to save runebook due to corrupted runebook

Since one week i cant change my rune because of my runebook is corrupted , and i also only use one of my two page of rune because the other is like a copy of my first so i have two different page of rune but both give the same thing when i choose it in the preparation of the games. So if anyone know how to fix that bug please explain me because i cant realy play because of that right now
