[RESOLVED] First Page in HTML help file

When I open the help file, which I have created, first page is being showed as the common error page of IE. (If you dont have an internet connection and try to open a web page it occurs...). Why? And How can I fix it?
(I use Microsoft HTML Help Workshop.)

Kinda vague. Did you create an Index?

no there is a part where I can make index list to search in help file but i want to set a html page as first page or main page. How can I do that?

you must set a default topic
