Vertigo,
I had this problem i thought.. i thought the mini kits were generated by the image of the kits, but they are not. The kits do work, you literally extract them to a folder somewhere and then copy the files to (HDD) C: Program Files/EAsports/EAsportsRugby 06. This is the main directory. The files will look like this..
g5jht454j64o6rk5or.fsh
jhfrsdghreligherilsdkjdsb.big
I dont know the actual numbers in the code but you should see them. You have to have to take the files out of the folders they come in (if they have one) and put the file into the directory.
And that's it.. dont look at the minikits unless you was uploading them.. the kit will be in the game when you play a match. [/b]
