Hi plangrph!
A picture of your plant could be helpful, but using only your description, I would think it could be a Phalaenopsis, also called Moth orchid.
My question would be, what kind of medium was it growing in?
I have found a lot of the time, they are potted in pure sphagnum moss. This tends to hold much more moisture. Did you repot into the same pot? Or a new one? Usually, when I have one that's showing a wrinkling of leaves, it's telling me that I've neglected it too long, and would like more water.
I have personally had more luck with a 70/30 mix of bark, and sphagnum, because I do tend to neglect them.
Hope I've been of a bit of help.
Please post a pic if you can.
