While installing and uninstalling did you deactivate your security software? Is there any registry protection software running in your system?
See whether you can restore back your PC to a date when your WMP was working.
BTW, I understand that you are a faithful user of WMP and so was I. Please allow me to suggest that you should try VLC media player.
I tend to use WMP for all my multimedia needs...I have other programs that either show video/DVDs alone, or play music alone, but have been a faithful user of Window Media Player for um-teen years now, and its never failed me ...until now.
The darn thing just won't open. I clicked on the shortcut on my Desktop; I clicked on it in the Programs List, the cursor changes to an hour glass for 2 seconds, then NOTHING HAPPENS..
I deleted it a few moments ago, re-installed it (from the Microsoft Home page), and still NOTHING! its like I didnt click on it at all....Please help / Feel like a fish out of water here...
