Therefore the update removes it: The package amslatex is split in amsmath and amscls. (Also there is a new package amslatex-primer): However, the update has not installed the new packages automatically. amscls contains the AMS classes (amsbook.cls, …). Just follow these steps: Create a file for the information you'd like to include in multiple files and name it something with a .sty extension, such as mylay.sty or mycommands.sty. If not, please download xcolor.sty and put it into your working directory or, better, the whole package xcolor. this contact form

You probably have been bitten by the same problem exposed in this question: tex.stackexchange.com/questions/96778 –egreg May 6 '13 at 22:14 Thank you! Now you are able to include your package in the usual way: \usepackage{your file name}, where you don't include the '.sty' in the file name in the \usepackage statement.
