RoboHelp 8 - Missing Browse Sequence

I previously created a project in RoboHelp 7.  I am now working on this project in RoboHelp 8, however when I generate it, it does not show the browse sequence.  The Browse sequence check box is selected in Window Properties, and I am on the same computer as before when I was working on it in RoboHelp, so I don't think the problem is with the HHactiveX.dll file, because it was registered from before.

Suggestions? Thanks.
