I've installed Windows 10 on my mac and downloaded replay media catcher 6. Unfortunately I can't download no video from truefire.
I don't understand how you managed to do so.

It download the .flv file with the same title from the video, but is merely 1,25kb size.
and some files the app can't download at all.
firefox is disabled in windows (same error as on mac: no secure connection). Only can use IE.
