Can't set password to encrypt iphone backup
When I try to set an encryption password for an iPhone backup in iTunes, I get this error message: "The password you entered to protect your iPhone backup could not be set. Please try again."
I've tried several different passwords, including upper- and lower-case letters, and numbers. No matter what I try, I get this error.
This is on a PC running Windows 7.
Any ideas? Thanks.
