Small N. Mira in trouble

[Ghan3sh]

Hi all,

I recently bought a nepenthes collection at czplants which included a small Nepenthes Mira. The Mira seemed to have insufficient humidity in the beginning so i placed it in a terrarium. I sprayed it with water every 3 days or so.
Today when i was going to water it i noticed that the newest leaves were hanging flacid and that the stem of the plant and part of the leaves had turned black. I guess the humidity must have been too high and that it has root rot or stem rot or something like that.
I received the plant somewhere in august and it has been doing ok till now. Since winter it wasnt growing as fast as it used to and it didnt pitcher but the leaves looked good so i thought it would pull thru next spring.
Can i still save this plant? What is the best way of treating it?

Here are a couple of photo's of the plant :
