Question about a Neglected Humidor

[Starscream]

I know there are already plenty of threads about this, but I couldn't find anything that answered specifics about my situation. I haven't smoked a cigar in quite a while, so I have neglected my smaller humidor. For about two years I haven't touched it. The digital hygrometer is on the outside, so I see the reading everyday, but I just never have gotten around to getting it back into shape. It has never dipped below 40 humidity. All summer it has been around 45-47 humidity.

My question is, "are the cigars in that humidor salvageable?" Is a low 40 average humidity too low to bring back to life? I always prefer to keep my main humi in the low 60s.
I'm not going to pitch anything until I get the humi back in shape, but I was wondering what to expect with the cigars.
Thoughts or recommendations? Thanks.
