Is there anything worse and more frustrating than spending several hours scheduling a few hundred renderings only to have (for reasons i still can't figure out) PV360 "Fail to Run" the renderings (it's the mesage you get in the status bar of the scheduler)?  There is no way to retrieve the schedulings, no way to "try again"...it simply wipes out all of your work in a matter of minutes.  The wierd thing is that I never had this happen in the Beta, but now that we have downloaded 2011, it seems to be happy pretty regularly.  Fun.
