Hi beldarski and welcome to our community
If memory serves correctly (and assuming Adobe hasn't changed
the playing field in this respect) I believe the trial has a limit
of 25 topics.
As for the RoboEngine bit, I'm not sure they even offer a
trial for that part. So my question to you is this. What output did
you create? If you tried WebHelp Pro or FlashHelp Pro and you tried
publishing that to a generic Web server (no RoboEngine in place)
I'm not sure what the behavior would be.
Cheers... Rick
