Were the leaves that fell off the bottom leaves or the center upper-most leaves? If they were the latter then you had crown rot that takes out the center of the plant - caused by getting water on the crown of the plant that doesn't evaporate quickly enough. If this is the case you are probably in for a very long recuperation period from this issue alone - I'm not talking months but several years - another new plant might be in order?. If you are fortunate and this was the case, you will eventually have a new start come up from near the media/plant base and start another "plant" (called a keiki). The normal cycle is for the plants to loose a bottom leaf or two coinciding with a new leaf or two growing out of the top/center. These plants DO want humidity (like most all orchids) and good filtered light - east windows or filtered if from other directions. North light usually isn't sufficient long term to get bloom. They typically bloom one cycle per year - they are forced by commercial growers to bloom pretty much any time of year, but their natural cycle (most) will be to start spiking in the fall or early winter and bloom in later winter or spring - usually for at least 3 months or so. The rest of the year we enjoy looking at the leaves, roots, etc. :-) Hope this helps.
