Well, I ask not because I can't/don't back up my ID(s), but because I would just rather not go to the trouble of a re-installation.
If it turns out that just using FLMM doesnt work, I always still have the option of a full clean re-install :)
But hopefully the simple FLMM solution will work (even if it does leave a few scattered fragments of this 'n that) and save me alot of time and impatience.:rolleyes:
