I am hoping you can help me I have recently got a 5th gen ipod nano and need to download iTunes 9 but every time I try I get an error saying
"iTunes + Quicktime" has an invalid signature. The download has been removed.
I am running the download using Internet Explorer 8 and Apple Software Update.
I have tried to download from Apple website and then on failing that I tried updating iTunes 7 to 9 and received the same error every time.
I have tried this on Windows XP also and receive the same messages.
