Recovering MAP file/ID after decompiling a CHM

Hi Sir/Madam,

I have decompiled a CHM file, the Context sensitive file is missing after decompilaion.

Could you help me recovering the MAP file from the CHM? or Is there any way to get the MAP file for the same?

Though it is a large file, its difficult to create the whole MAP ID manually as we are in the final stage of project release in our organisation.

It will be really helpfull if i get any solution. 

Thanks in advance.

Regards,
