Scheduler not available CC 1.4.1

When Campcaster 1.4.1 was fresh installed scheduler started fine (no more errors) but once I changed the sound card preferences and re-started, the scheduler doesn't start and often when it does start it does not appear when I click the scheduler tab. Strange eh..

i can restart at terminal but surely there is something up my system. where should I look to fix?

Thanks
John
