Portable Firefox and Windows Media Player

Lately, I've been having problems with WMP working on my browsers. It doesn't work both with Portable Firefox nor Internet Explorer. It doesn't play any kind of streaming media. I always get this "Please verify that the path or filename is correct" error or "The specified stream is not recognized" error. The weird thing is the WMP interface in my browsers is that of the old version of WMP.. you know the black and brown one but I have WM10 installed in my PC. WMP works perfectly on its own... I only encounter trouble with it when it comes to browsers. I'm totally clueless about this so I really need your help guys.. I really appreciate it if anyone can help me. Thanks!
