I bought one of these last year, and mine sulked much like yours until I figured out that it has somewhat different cultural requirements than most Paphs. Bright light (more than your average paph or phal) but no direct sun, intermediate temperatures and high humidity during the summer/fall (lower during the winter). It needs fairly heavy watering, but it also needs to be potted in a very fast draining medium as the roots will rot quite easily if kept in wet/stale conditions. Watering should also be done with distilled/RO water (minimally fertilized) as the roots on this one are particularly sensitive to salt buildup. If you can't go that route then the pot should be flushed frequently to prevent any buildup.

When I changed the growing conditions on mine the original growth never perked up, but it has since sprouted another wich so far has three healthy leaves and another starting to peek through the crown. Hopefully it will bloom for me this year.

Hope this helps. Good luck!
