iTunes error message. Cannot open or sync
I've been having problems with iTunes since downloading the new software for os4. I upgraded my iTunes to 9 and it worked once, in order to complete the software upgrade on my iPhone. Now every time I try to open iTunes it comes up with an error message
Cannot create the directory 'C:\ProgramFiles\iTunes\iTunes.Resources\ja.lproj\ DevicePrefsRingtones.nib'
A file with this name already exists. Please remame or remove the file and click retry or cable to exit.
I have tried looking for the file name and i can't find it, it doesn't come up in a search nor when I manually look for it. I can find other file pathways but not the ring tone one.
I think the problem has occurred after I downloaded a ringtone from a non apple site.
I'm unable to open iTunes at all. I have tried downloading a new version but it gets halfway though download and say that it already exists. I don't want to delete iTunes as I will lose all my data.
It has also corrupted my iPod function on my iPhone and that no longer works.
I hope I have put enough detail in my post for you to help, this is my first time posting!!!
Thanks.
