I want to Play F.E.A.R. But I Can't, Help Plz?

[yamato]

My FEAR disc is scratched and I have a backup, the program to generate the CD key isnt working, and I found one on internet, it works fine but when i wanna open it, it wont let me, says that the original copy couldnt be found or isnt validated. I found something about Anti-blaxx, but cant make it work, all the websites i've visited send me to this link:

http://m0004.gamecopyworld.com/games/pc_fear.shtml#F.E.A.R.%20Director's%20Cut%20v1.02% 20[ENGLISH]%20No-DVD/Fixed%20Image

My game is directors cut edition, and i wont pay 55 bucks again for it, so.. this link explains what programs to download etc, it says run this and that, example:

F.E.A.R. Director's Cut v1.02 [ENGLISH] No-DVD/Fixed Image 18-11-2005

DAEMON Tools
Image Tools - SR7.Stop & AntiBlah

Play Instructions:
Install the game - Full Installation.
Use an anti-blacklisting tool, SR7.Stop or AntiBlah, to avoid SecuROM v7 from blacklisting DAEMON Tools.
Mount the FEAR-MINI.MDS DVD-Image in DAEMON Tools v4.00.
Play the Game!

This is what's needed for my game's version, but cant make it run cause i dont know how to configure it. I install everything but it keeps on telling me the same. Anyone can tell me how to do it? Explain me how to use it for my game. All the sites i've been to tells me what to install but doesnt say how to use. If anyone could help me, its super appreciated thanks a lot!
