SO AWESOME !!!! it s damn crazy !!! exellent
to fix your problem with maya i hvae a "crazy" solution but i do it many times when i have so problem with maya.
uninstall maya with the uninstaller. take your folder calle maya in your user/document/maya and rename it and move it in an another place. then launch sherlock and type maya and remove all the files with "maya" included in the name. the reinstall maya with maybe the license then it must works !!!
