Standard and 3d kits

Hi guys,

Today I playing around with in-game editor and I decided to change Benfica's first kit. The sole purpose was to change the colors in the tactics panels, as I already had the FC12 kits and the 3d kits installed. However, doing this, both kits don't work anymore. Basicly, I want to use the FC 12 kits and the 3 kits I downloaded but, I would like to change the kits' colors in the tactics panels without damaging the previous 2. Is there a workaround?
Thanks
