This program obviously has something wrong with it for wp 3.1.1 First, it mass publishes everything in draft status as soon as you update the schedule. If items are placed into draft status after the schedule has been set then it is safe, so safe that it isn't getting published based on the scheduling parameters given.
I emailed the author and he agreed that there was something different about wp 3.1.1 and that he wasn't able to find the fix yet. The next day I got an email telling me that he couldn't find the problem but everything seemed to be working fine on his end.
Ummm ... it's not working fine on this end. :(
