Problem with .ecm files

Hi first post w00t w00t... Anyways, I'm having a problem with one of the FF files. It was decompressed as a .ecm file, so I got another program that decompressed that and put it into .bin.ecm format. my epsxe 1.7.0 enhanced recognizes the file and gives me the option to open it, however, when I open it, all I get it a black screen with no sound or picture and then it freezes? Is there a plug-in I am missing? Thanks
