Today, for some reason, when I tried to open iTunes, my iBook running Tiger told me that I lacked permission to open it. Looking for the quick fix, I moved iTunes to the trash, and emptied the can. I redownloaded the software and tried to install it. Upon doing so, the Installer said it was going to skip the install. It said there was no need for it. I started thinking that some fragments must still exist somewhere. However, I don't know what to do now? Any ideas/suggestions? Thanks!!!
