Ok, am a dope. I read all instructions wrong and was looking in the wrong place for "Change Settings" Seems to be fine now

Am using W7 Enterprise SP1, acting as guinea pig. Have run Backup/Restore but have a couple of problems: 1. Having selected my own files to backup, the backup froze on 12% completion 2. When I go back into Backup/Restore to try and change the files I'm backing up to a much smaller sub-set, the "Change Settings" option is nowhere to be seen. I don't mean it doesn't work (like some other posts on here), I mean it doesn't actually exist. I'm comfortable changing registry entries, and have exported the Reg Key (HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsBackup) in .txt and .reg formats if that helps anyone have a look-see? Anyone help? Cheers
