Windows DRM Probs

I've come to the conclusion that there is a problem with my pc when it comes to stuff with drm on windows file.
For example when i try to play something from iplayer, media player freezes and shuts down.
Even when i right click the files and select propeties it's fine until i select license and then it saw windows explorer must shut down.

When i try to watch something on channel 4 on demand it freezes the moment the media player window pops up.

What should i do. I'm running Vista Home Premium 32bit and have all the latest update installed. I would reinstall media player but you can't do that on vista.

Update: Cleared out my drm folder and it works fine now.
