(FOR ANYONE WHO REACHES HERE)
All you had to do was, download wma9dmod.dll, put it in the 32 bit and 64 bit system directories (for both types of programs), click/double-click on the file once from both directories to register it into the windows registry, and you are done.
Of course I reached this conclusion after I had this problem, and started reading this thread and searching the Internet. Nowhere was written this clearly. When I concluded this, I did this and I was through.
I already used to keep a copy of wmv9dmod.dll with me, from a previous problem where videos would not work.
Thanks
