and find the itunes music library.
Move it somewhere safe, outside of the music folder.
Uninstall iTunes and reinstall it
Once you have it running, copy the copy of the itunes music library back into the music folder, overwriting the newly created one.
Last night I decided to update to iTunes 9.1.1, via the software update prompt. It prompted me to restart my computer (laptop, Windows Vista). I proceeded to do so, but it got hung up in the log off screen for over 15 minutes. I turned off the computer and came back into the desktop. Tried to load iTunes, but it wouldn't load anymore. Tried to reinstall the software update, but now it's searching for a .msi file that I have no idea about? Anyone have any input as how I can resolve this, and have I lost all of my music in iTunes at this point? John
