Updating drawings using task scheduler

I have about 200 drawings that I need to simply update because one dimension changed.  I have tried to do this in task scheduler but i get a fail message everytime.  My drawings have custom properties for the regular stuff on the title block, but there is nothing out of the ordinary.  Are there any settings that I need to have on or off?  Please help!
