GO TO THE LAST 2 PARAGRAPHS IF YOU DON'T CARE ABOUT HOW I DISCOVERED THE PROBLEM.

So I JUST had this problem happen to me after having had WMP 11 work great for months. I hadn't even changed my software in weeks before this randomly happened. I had WMP 11 delete the entire library and it wouldn't let me add any monitor folders, as described by some of you earlier in this thread.

I took Carrotglace's advice on how to fix this by deleting that folder and creating a new one, and it worked. But, like he said, I had to rebuild the entire library. This causes you to lose all your add dates for all the media files as well as your recently added list (which sucked for me, because I regularly utilize that info and list). SO, what I did was just go through each of the files contained in that 'Media Player' folder and looked through the properties of each file taking note as to which file might have been modified at right in between when I last had functionality and when I lost it this morning. I actually found a file that had been modified at the right time. It was the 'wmpfolders.wmdb' file. I really don't know what exactly the function of the file is, but I opened it in notepad, and systematically compared it to the new file that was created after I created the new 'Media Player' folder and had ran and shut down WMP 11 a couple times. I noticed that at the bottom of the coding, it had a couple lines that had exclude values set to "-1" instead of 0 as in every other line in both documents. So I changed the values back to 0 and reinstated all the old files contained in the old "Media Player" folder, and BAM!.... Functionality back! AS well as all library data.

LONG STORY shorter, apparently WMP 11 modified some code in the "wmpfolders.wmdb" file at the bottom of the document (opened in notepad) to have exclude values set to "-1" instead of 0. In my case, it looked like they were playlist and sync lists that were all of a sudden being excluded from being the same lists as my Zune software uses, thus causing WMP 11 to seemingly delete the entire library.

Everyone who has had this problem has probably, at some point leading up to when they had the problem, installed some sort of new media software... Anyways, go through that file's code and change those values, and you should be good.

Hope this helps.

When I try to follow your directions about deleting the media player file I get the message "Cannot delete CurrentDataBase360. It is being used by another person or program." Now what do I do?Please help and Thanx.

Still not entirely solved

I have the same problem as described - everything wiped from the library, unable to add any files, folders disappearing from the add list as soon as I close the dialogue.

The first solution given - the one to delete all the files - I have tried and it doesn't work, when I relaunch WMP it doesn't rebuild them, it just leaves the folder empty.

With the second solution - I restored the files from the bin and looked for wmpfolders.wmdb - that file doesn't exist on my system.

Has anyone got any other suggestions?

Cheers.
