Weekly Schedule not working

Hi guys, I'm evaluating SyncBackSE. So far the only problem I've found is that I can't get the sync to work. The profiles run ok if I start them manually,and the documents folder, which I update daily, works fine with the daily schedule. However, the other profiles which I've scheduled to run weekly just don't run automatically. I get an error message saying "The task scheduler attempted to run the profile but the task did not run due to one of the constraints in the task definition". So I guess this is just something in the way I've set up the schedule.

Can you please tell me whether in the weekly schedule you also have to click on the "Repeat" tab at the bottom and select to run "every 7 days" and "Indefinitely", or should it be enough to simply select the weekly schedule tab and click every 1 week and a day?

Any other ideas what I might be doing wrong?

Thanks,

Trevor.
