Windows 7 has been installed on this PC for about one month. Today is the first time I tried to use Media Player. I cannot create a playlist. When I try I get the following error message: "Windows Medial Player encountered a problem while creating or saving the playlist" I have tried turning OFF/ON Media Player in Control Panel. I have run sfc /scannow with no problems found. I tried system restore. No difference. Looking for suggestions to fix this problem. Thanks.
