I tried this procedure and it made no difference at all. I contacted tech support and they suggested re-installing the software. That didn't help so I tried this fix again and still had no access to help withing Premiere Elements 4.0.
Then I got an idea ...
What if I used a help client from some other adobe software such as acrobat reader 8 for example.
Low and behold, I now have hlep running in Premiere Elements 4.0.
