Glad you got the problem fixed.
What I do is to take some liquid Certo (find it in the baking section or canning supply section of the supermarket) and a small artist's brush (I use a cheap, fine bristle one from Hobby Lobby, Michaels, etc) and just paint the crack with it. Let it dry and you're all set. This works for loose wrappers as well.
Certo is basically the same thing as what's used to affix the wrapper at the factory, so it won't hurt anything, and doesn't add any flavor whatsoever.
