No need to re-start, you will only obviously miss the new advantages since you already have picked those and few of the fixes (from JOG) won't be applied. Other than that, everything should work.

@wolfling: This should work with all the game versions, as long as they are v1.1 (shows in bottom right corner when you start the game).
