I am not new to TeX in general, but very new to TeX on Windows. In the past I always had a Linux system at hand to create my documents in TeX. However, I don't have that opportunity anymore and want to create TeX documents on my Windows (7, 64 bit) machine.
I looked around for a bit and downloaded ProTeXt (http://www.tug.org/protext). Installation went fine (meaning there were no errors reported by the installer). So I open TeXworks, open a .tex file that I had created a while back and hit "Typeset". Shortly after I am informed that
scrreprt.cls is missing. So I open the package manager to install
koma-script. As soon as I hit the
install button I see a new window that downloads something, however the status bars don't move and the
update statistics are empty (=no numbers at all). After a few seconds the whole thing freezes and I get another window saying "MiKTeX Package Manager has stopped working". Any kind of help is highly appreciated!
