[MiKTeX] Problem with using listings package

[<fra...@gm...>]

Hi all!
I am new to MikTex (version 2.4). I am using Texniccenter. I am
writing a project report and need to include some code listings. When
I try to use the listings package \usepackage{listings}, MikTex tells
me that the packkage needs to be installed. So far so good, I agree to
the installation from the Berlin repository server and it seems to
download something. Afterwards however, it complains that the
patchfile lstpatch.sty is for version 1.3, while I am using version
1.0. ??? Why am I downloading the wrong version and how can I get the
right one? I also tried to use te package manager to download the
listings package with the same result. Please help! I dont know what's
going wrong here. Thank you!
