I'm using the german version of Wizard 101 under MacOS X 10.6 (Crossover current release) on Linux (Crossover 11.2.0) and natively under Windows XP. There was this big update on Sep. 17th which probably implemented the new world Avalon, new levels etc. After this update the game cannot start anymore on both the Crossover versions on the Mac and on Linux. It seems to be unable to download the wad-Files in the Login screen. The left progress bar goes up to nearly half of the files then stops and tries the next one - without success. The right overall progress bar doesn't show any progress at all. After a minute the original login screen returns. On my Windows PC everything works as expected.
