WMPlayer7

My operating system is Win ME. In the beginning I could play CDs in WMPlayer then it was giving me a message: WMplayer has caused an error in the MSISAMll.dll file it will now close. I can play other media files and go through file open to access the tracks, but it will not open when I select CD Audio it say it does not support that format or just remains dead. I have uninstalled and reinstalled the player and still cannot get it to perform right the MSISAMll.dll file message keeps surfacing.
Thank You
