We had a problem with SP1 Help. The path in the Start Menu shortcut is wrong and it points to Microsoft Document Explorer 8 and it should be 9. You should go to properties of the Documentation shortcut and change the target path from "Help 8" to "Help 9". Another way is just to start ViewHelp.bat from the documentation folder.
This should fix the problem. Sorry for the caused inconvenience. This was fixed in later releases.
