I loaded OneNote 2010 on a Mac running Parallels. Since installing, I cannot add notebooks or pages without getting these error messages: First, there is a yellow bar at the top that says: "This section is in a pre-release format of OneNote. This section is corrupted. ENTER to repair. I hit enter and get:"OneNote cannot access the cache file. It may be corrupted. OneNote will restart and create a new cache file. Error Code: 0xE00013C" I then click OK. I am given the choice either to delete cache or make a copy. Which ever I choose I am left where I started.
