Every time I try to update iTunes, my computer tells me it has an invalid signature and removes the download. What can I do?
Every time I try to update iTunes, my computer tells me it has an invalid signature and removes the download. I have tried "download only" but the same thing happens. I currently have iTunes 10.5.2.11 and my OS is Windows XP. Also, the iTunes DJ function has frozen on one play list and will not change playlists, nor will it refresh and rearrange the songs.
