Solve : library not registered????

1.	Solve : library not registered????
Answer» I ran into this first when trying to watch a vidio onlie using Windows Media Player, but EVERY so often a warning box comes up stating "Library not registered." I dont even know what a library is EXCEPT song library in Real Player or Media. Also, when I went into "Control Panel" then "Admin Tools" then "Local Users & Groups" it has a red circle with an "X" in the center. When I click on that it comes up "UNABLE to access the computer _______. The error was: Library not registered." Please help a "geek wannabe" know what to do?? TKS, SACan you please provide more information? (ie. Windows version, media player version, etc.)
