I am having problems with WMP asking for a plug for Windows 7. It says I nee to download the 'Microsoft® Windows Media Services" plug-in, I can find one for XP but not W7... Any ideas for what I can do?

I keep getting a message with fully purchased CD's that I cannot rip them to WMP or iTunes (actually iTunes doesnt even recognise them as a cd) as I dont have a licence for them. I then try to download the 'licence migration' and am advised I dont have the plug in to do so, but cannot find the plug in from MS. I have downloaded the Windows Media Player Plug-in for Netscape Navigator (wmpplugin.exe) but it won't run on W7. (And of course doesnt include firefox...) Any assistance gratefully received...
