Paph. with White Mold/Rot? Help!

[mtayl04]

Hi,

I got this orchid about 3 weeks ago at a home improvement store, this is my first paphiopedilum. The moss it is in was packed very tightly up to the bottom leaves, so I loosened and removed some to alllow a little more air circulation. A couple of weeks ago, I noticed a white fuzz on the main root that is visible, so I tried just wiping it off. It came back and I searched around and people recommended to use anti-fungal or cinnamon. So I spread some cinnamon on the root. I tried to keep it off the base of the plant, but of course, the white fuzz went all the way up to the base. 3 days later, the white fuzz is back in full force, and there is also some browning at the base of the plant. I don't know if this is from the cinnamon, or some sort of rot issue. Also, the flower has died, but it could have been an older bloom when I got it from the store, I have no way to know! The flower is in moss (the rest of mine are in bark) so I may have been overwatering it for the first week or two...would that contribute to the fuzz/rot problems? I am holding off on watering a little lighter to help. The rest of the plant seems healthy as far as I can tell. Can I get rid of the fuzz? What is it? Is my plant rotting/dying? I plan to repot ASAP, I just want to make sure I fix these problems before I move it to new media! Thanks!
