Have you seasoned your humidor recently? A good seasoning fixes a lot of problems. The wood soaks up moisture, expands a bit and then seals much better. Sometimes that's enough to fix everything and sometimes it's not.
I would recommend taking all your cigars out of your humidor and putting them in a Ziploc or Tupperware container -- they will be fine for a few weeks.
Next, thoroughly season your humidor. Use a wet (distilled water) sponge. Let is season for at least two weeks. If you have a
good hygrometer you can throw the hygrometer in the humidor and watch the RH. After the seasoning you can check the seal around the lid, in the corners, around any glass or embedded hygrometers and fix them.
Finally, pick up some beads or Boveda packs or whatever you choose and the put the humidification device and your cigars back in the humidor. Let it all sit for a couple of weeks.
The biggest thing you need to learn with cigars is that you need patience. Lots of patience. Nothing happens fast with cigars -- and you don't want it to happen fast (fast changes result in damaged or split wrappers).
So let things happen slowly -- give each step weeks to settle out.
BTW, now you should have a cigar
