Alas, this is why when venturing into foreign territory, it behooves one to immediately do some research rather than assume the new plant likes the same conditions as all the other ones one possesses.
Whether it can be saved depends upon how far gone it is and what conditions you can provide. A Google search should give you some avenues to explore. Many if not most of the pleuros detest drying out and must be kept damp (not sopping wet). Bark can be done but, IME, is harder to keep moist enough. (But again that is in MY growing conditions which could well be radically different than yours.) This orchid prefers cool (even cold) to intermediate temps -- so nothing above the low 70s F, and more likely preferred in the 60s.
Too bad its fairing poorly, this species has delightful little flowers.
