All '09 downloads work. Facepacks, logos, kits, 3D kits.
All you need to do is: In your FM10 folder create a new folder and name it graphics.
Click into here and put in 3 sub folders name them: logos, faces, kits.
Put your downloads into here.
Then on the FM10 start screen, go to preferences, untick. 'skin caches' and tick 'always reload caches on confirm.'
Wait for them to load up and away you go!!
Some may have quicker ways to do it but I've got it to work this way.
