I'm trying to use the package pgfplots, and I have successfully installed it along with the pre-requisite pgf. Whenever I compile, I get the error message "The required file …everyshi.sty is missing", and then nothing works. I am using a Windows (64bit) computer with MikTeX 2.9 (when I installed it, I only did the basic set up). I am using TeXnicCenter as my environment. Help would be much appreciated. Thank You.
