Just for information, After installing 1.5.1 I was unable to read properly some documents because the class is missing in the standard installation package. So one way is to: Go to Start (is it start in English, the left button at the bottom corner of the screen)program -->MiKTeX.6-->Click on "Browse Package". Then you will get all the available packages and you will see which one are installed in your MiKTeX. Then you can select the one(s) which is(are) missing and click on the button "+" which is at the upper left corner of the window. Then and if you are connected to internet the package(s) will be automatically downloaded and installed. If I remember properly that option was already available in the former MiKTeX. Paul > >
