I use my Mac Help quite a bit, but today when I went to use it, all I got was a white screen. The search field and the navigation buttons were still there, but nothing would happen when I entered a search and it wouldn't go to the Help 'home' page. Have I deleted a file or folder somewhere?

Try the following:
In most cases doing the following will restore the Help Viewer:
1. Trash the following three files, if extant:
/Home/Library/Preferences/com.apple.help.plist
/Home/Library/Preferences/com.apple.helpui.plist
/Home/Library/Preferences/com.apple.helpviewer.plist
2. Trash the /Home/Library/Caches/com.apple.helpui folder.
3. Empty the Trash and Restart.
