Ok,
No problem about the caps.
In Vixen scheduler.
You can use either the program (you defined the list of sequences) or just schedule the sequence.
Either way you have to set the time you want to start. Once that is done go to the last tab in Scheduler and look at the Agenda view. It should show your start and stop time.
Make sure the check box is unchecked (Disable the schedule)
To be honest I fought with Vixen scheduler for 2 years, The first year it was a hit or miss, but mostly a miss.
This year I am using xlights to run the show and use Vixen to program the show. So far it xlights seems to work, once you get used to how it works.
Hope that helps or at least gives you ideas where to look
Cheers
