nah ive got them to disappear by doing this:
1. delete the kits in editor data directory (Football Manager 2008\FM 2008\editor data\kits)
2. Download the rar file
http://www.sendspace.com/file/9ry2gf and extract it in the same kit directory
3. Create "default" folder in the Graphics folder where you have put your kits (My Documents\Sports Interactive\Football Manager 2008\graphics\kits by default)
4. Copy the content of the kit folder in editor data (your first step) and paste it in the "default" folder
5. Restart the game ...
should work fine...
