BibTeX, biblatex and biber ⇒ Unable to add a specific bibtex style to MiKTeX

[atpase]

Hi there

i have a problem in adding a specific package to miktex

I'm using miktex 2.8.3478 for organization of bibtex4word
i want to use a specific citation style within this appplication

it can be found here:

http://www.ctan.org/tex-archive/biblio/ ... 1c60604d8e

it is the pnas2009.bst

but i cannot find this in the package manager
i tried to do the repository via internet on different servers - but i couldn't find it in the manager
i tried to download the whole folder misc.zip manually to do the repository via a directory - but this didn't work too
there i always got the note that the folder is not suitable for repository or something like this

where is the problem

thanks a lot in advance and I hope I gave all needed informations to solve the problem
