Paph roots in bad shape - need help

[Phyrex]

I have a paph that is just sitting there with two new growths. The old flowered growth has completely disintegrated already. I pulled it out of the pot to check the roots and there might be one viable root left. What can I do to get it to grow some new roots? Should I keep it dry compared to before, should I add rooting powder, put it in a darker spot? I don't know what to do and I don't want to lose this beauty. Any help is appreciated.
