Windows 7 Task Scheduler Errors

[UnclKracker]

I'm not familiar with task scheduler. I was going to create a task to backup my Stickies notes to my Dropbox but when I opened Task Scheduler these two errors popped up. I clicked OK on the first one then the second one appeared.
Can someone shed some light on what's causing this and hopefully what I can do to repair it?
My system is Windows 7 Pro x86
