Vista - media player + mobile device centre

I have two problems with two separate applications, media player + mobile device centre, which I think have something to do with networking.

When I tried to add media to the mediao library in windows media player, it goes through all of the process, it does not throw up any error messages, but when it has finished nothing has been added. It doesn't matter from what source u add the media, i.e. A network, hard drive on the laptop, or an SDard. Like wise through my windows media player I cannot add any music to my pocket PC.
I am able to add the partnership between my pocket PC and my laptop in windows mobile device centre, again it goes through all the processes without throwing up any error messages, but when it has finished nothing has been synced.

I have tried downloading the software for mobile device centre 6.1, and installing it. When I have installed it in the device centre helped menu/about it says "Version 6.0 (build the 6001: service pack 1)"

Any help would be appreciated.
