Couldn't agree more with you both.
It was the pure shock factor.Used it for ages and love the program but this is the first time its made an error at least for me.The key word here I think is "complacency".You presume as its worked well for you previously everything will be ok.
@Mindinka - Yes the restore point and reg backup is a great feature of Revo allowing for mistakes to be rectified. No ones invincible.
@Kadu - Check everything seems like good advice and NEVER get complacent. Interesting you had the same issue with it finding unrelated entries.Like I said its never happened to me before and now two instances in one day.
Still a great product though
