The fdm project is dead. The Sourceforge project page returns 404, and the Github repository hasn't been updated since 2014. (And the Sourceforge mailing list returns 404 as well.)

The code probably works, but don't expect any help or updates.

I used it a couple of months ago and it worked perfectly.

Not all dead projects are actually dead. Some are just "completed".
