  • @HarishKumar, strange. texless tikz-cd returned \ProvidesPackage{tikz-cd}[2012/12/30 v0.3c Commutative diagrams with tikz.]. – Sigur Jul 18 '14 at 0:15
  • @HarishKumar, I found the problem. I don't why but somebody saved a tikz-cd.sty old file on my home folder. I deleted it and now I'm loading the updated one. Thanks. I'll delete my post soon. – Sigur Jul 18 '14 at 0:18
