Need help with adding cars to Race 07

[bsmooth]

I've tried doing this with 7Zip,WinRar and now Winzip, and still get nothing.
Basically I'm trying to add these mods:
Mazda MX-5 Cup
Formula Ford 2011
F1 Formula Legends.
After extraction I get this message:
Extracting to "C:\Program Files\RACE 07 Offline\"
Use Path: yes Overlay Files: no
Error: Unable to create "C:\Program Files\RACE 07 Offline\Mazda Mx5\GameData\Teams\Hankook MX5 Cup\DATA\3rdp_hansdevice.gmt"
Irrecoverable Error: File creation error.
If I can't do it by extracting it directly into Race 07 Offline, can I do it manually, and how do I do it ?

There is a guide in the Mod section, hopefully that can steer you in the right direction. I only use online version.
