Epidendrum Burtonii in Bad condition.. Help!!

[ana22]

Hi all,
I acquired a cheap epidendrum burtonii yesterday. I felt sorry for the plant, so I bought it. There are two cuttings one small and one fairly large with roots along its length. Also the previous owner cut off the flower spike. Can the flower spike grow into a plant?
Also the leaves of the larger cutting have brown spots, they look like scale insect attack, but I read something about a fungus which attacks their leaves.
Could anyone give me any advice on how to make these cutting survive?

Thankyou
Ana
