4 x Chroma packs not working

Have tried going into custom games and normal drafts with the chroma skins (Nasus/Vayne/LeeSin/Blitz) looking like they're on. Get into game and i just have the basic skin. I've had a proper look and it looks as though the skins themselves although i have them "highlighted" are not activating on champ select screen. Help please? :/ - Regards, Kharmah (EDIT) - Nasus is now the only one not working -.-
