I'm using the free EmEditor 6.00.4 on Win XP Pro SP3. Sometimes, when I click Help and choose a topic I get the Help text. Other times I get an error message:
==== begin error message ===
This program cannot display the webpage

Most likely causes:
You are not connected to the Internet.
The website is encountering problems.
There might be a typing error in the address.

What you can try:
Check your Internet connection. Try visiting another website to make sure you are connected.

Retype the address.

Go back to the previous page.

=== end error message ====

I always get the same result for the same topic; in other words Help is always available for some topics and never available for others.

Whay is happening, please?
