The vanishing tunes is very common on Windows PC when Windows Media Player is set to rearrange my music. Are you sure that you turned that off and there are no external drives?
Itunes must have automatically installed this new version. When it opened all my music was missing that did not come from apple. I reedited my prefrences/advanced and checked both,"keep itunes organized..." and "Copy files to itunes Media folder...". Then I can find and add my music back into itunes. It plays, I can create playlists... but when it reopens the new music is gone and the check boxes are empty. This has been going on for 3 days and I have no idea what is happening. I am not great with a puter so please if you have a solution give detailed instructions. Thanks TP
Here's the setting of interest -> http://answers.microsoft.com/en-us/windows/forum/windows_7-pictures/why-is-media-player-12-is-rearranging-my-music/4b61da39-348f-4d0b-80aa-fe42e5da0a08
" When I started MP12 for the first time it immediately started scanning for media files and rearranging them, without warning and without asking.... By the time I configured it as I had in previous versions (i.e., like you just suggested), which only took me a couple of minutes, it already had done some damage."
I'll skip writing about backup.
Thought the wmp settings were going to work, it seemed to run fine, iclosed and reopened it with no problem. Made several playlist to check it tomorrow, closed it and reopened a bit ago and itunes will not even open now. Tried to run as admin, would not open. Went to add/remove programs and it appeared to be there or at least taking up space. Any thoughts?
