how can I save my playlist with an m3u extension? Thank you for any help

I have Windows Media 11 Beta 2 and it seems to work fine, but there is a
small bug that annoys me a lot.
When I pass my mouse over one of the music control buttons (play, pause,
etc) or one of the library buttons (Library, Sync etc), it lights up to

I cannot play files off the internet.
I tried the command "connect to internet (overrides other commands)"
I tried just about every suggested solution I could find on line.  I turned
off the firewall.  The only thing that worked was to go to safe mode with

WMP11.  Go to the support page (http://usa.philips.com/support) and

crashes while loading when I want to start it, without any error notice.
What could the problem be? How can it be solved?

I don't know what's going on, but since I installed the latest beta WMP11
crashes for seemingly no reason.  I get the "send error report" dialog and it
forces it to close.

but the downside is using Windows Media Player, I don't ...

I can't find my original post below is it quoted. It was suggested that I
install SP2. I reluctantly did that and it took several hours to do. Did not fix
the problem below, didn't even help it. I've removed and installed WMP 10 four
times now. Does anyone have any suggestions. Read ...

I recently downloaded some MP3 audio from a legit source (Projo.com) and

also presented with an UNBLOCK buttom.  I am able to play ...

I use Windows Media Player 10. My problem is that the player deletes items
from my library. The files are still in the folder My Library, but they are
no longer in my library in the console itself. It's a pain because I have a
lot of files and I don't know which are deleted; I ...
