Masdevallia 'Angel Frost' Problems

I have a Masdevallia 'Angel Frost' that I got in March of this year.  I got it Colorado and brought it back home.

It flowered and did fine until about a month later when it started to loose all of its leaves and I had three leaves left.  I started putting it in a wine cooler at night (at 53 degrees F) and leaving it in a small greenhouse with about 70% to 90% humidity during the day and about 75 degrees.  It started to grow back one small leaf back but then the new growth died and two leaves fell off.

I am not sure what to do now and if I am doing everything right.
