Re: wmp ,nothing works
thank for the reply but i have already solved the problem.
i found out that all the libraries were shown as unresponsive,therefore i was getting this problem.since liraries were unresponsive,there was no effect on them whatever i want to do.
so,i removed all the folders included in the libraries and tools>advanced>restore media library.afterwards my library was empty and then i included the folders that were in my library before.
problem solved.
