More clues would be required to dig into this. We know that WMP has issues but here we have not much to work with.
Try this. Login to your other Admin account (windows users know why we keep a spare) and test it there.
I have win 7 home premium and the media player quit working. It makes a beep and message says it encountered a problem while playing a file and a red x comes up to the left of the name of the song. I turned it off and then back on using the windows features and did sfc/scannow and got cbs log that doesn't mean anything to me - none of this worked. Can I download the media player again or will I lose all the songs on there? Or should I just go with something like VLC? Thanks in advance - I haven't been able to reply to any answers I have gotten from posts in the past.
