Right click on the object, then go into the menu 'Realtime Effects' and you will see it towards the bottom 'Elastic Audio Easy'. Alternatively you can get to it by double-clicking on the object to bring up the 'Object Editor' tool and on the left side you will see 'Pitchshifting Timestretching'. Click on that and you will enter a new menu. On the bottom right you will find a button 'Elastic Audio'. Click on that and it will take you to the editing screen. If neither of those methods work I'm not sure what's wrong.
