Guide To Error C00D11D4 In Windows Media Player
Error C00D11D4 or Invalid Request can be solved many times by un-checking UDP under Tools>>Options>>Network. Then Close WMP then re-open it. Try to access the content again. This error has also been linked to bad proxy settings. You might also make sure that you don't have a firewall blocking WMP access to the internet. I have also seen people report check "Connect to the Internet" under the main options of WMP fixed this.
