iTunes Rental Woes … and a Solution

I rented Forks over Knives on iTunes today (great movie – the information presented is very compelling), but every time I tried to start playing the movie I got an iTunes error (-42110). Apple’s support forum was less than helpful about a solution, so I turned to the wisdom of the greater internet, and found this informative page ; simply shutting down iTunes, nuking the /Users/Shared/SC Info, and restarting iTunes solved the problem.
