How to find the Missing Fonts in Indesign

Question

Hi All,

When I open the INDD file in indesign, some of the fonts are missing, Its showing only the substituted fonts when I clicked on "Find Font" button instead of missing fonts.

1. Where can I see the original font used in the particular text?

2. I have pasted the missing fonts loader plugin in the path "c:\Program Files\Adobe\Adobe InDesign CS4\Plug-Ins\MissingFontsLoader\MissingFontsLoader.pln" even thought its showing the same, substituting its own fonts?

Can any one tel me how to solve this issue? I want to use the same font in the document.
