Hello! I used the tikz package to draw diagrams free body (dynamics and Newton's Law for exercises), the problem that I have is the next error when compile:
! Argument of \language at active@arg> has an extra }.
<inserted text>
                \par
l.148     \draw[->]
                    (base)++(\arcr,0) arc (0:\iangle:\arcr);
my preambule is (to long...):
\documentclass[12pt,a4paper]{article}
\usepackage[a4paper,left=3cm,right=2cm]{geometry}
\usepackage{verbatim}
\usepackage[spanish,activeacute]{babel}
\usepackage[utf8]{inputenc}
\usepackage{fancyhdr}
\usepackage{scrextend}
\usepackage{upgreek}
\usepackage{enumerate}
\usepackage{times}
\usepackage{gensymb}
\usepackage{graphicx}
\usepackage{textcomp}
\usepackage{etex}
\usepackage[intlimits]{amsmath}
\usepackage{tikz}
\usetikzlibrary{scopes}
\usepackage{cancel}
\usepackage{subfigure}
\usepackage{amssymb}
\usepackage{amsfonts}
\usepackage{dsfont}
\usepackage{float}
\usepackage{capt-of}
\usepackage{captdef}
\usepackage{dialogue}
\usepackage{pst-all}
\usepackage{pstricks-add}
\usepackage{pst-circ}
\usepackage[siunitx]{circuitikz}
\usepackage{circuitikz}
\usepackage{hyperref}

but!! when I compiled with only

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{scopes}
\usepackage{verbatim}

it compile the graphics perfectly, this packages I charged in my preambule, but I can't understand why not compile.The example to free body diagrams took out it of:
http://www.texample.net/tikz/examples/free-body-diagrams/

The art to tikz is really complicated

Thanks a lot!
