Paste mocha mask generate mask but don't move it

Hi everybody! I’m new to Mocha and I’m having some trouble with shape. In Mocha I create one layer with rough track as reference shape and I attach to it a finer roto in another layer. Then I click on Export Shape Data… and then to Copy to Clipboard. After that I switch to After Effect CS5.5 and use Paste mocha mask on a video in my composition. The mask appear but, and here there is a problem, when I play the video, the mask still in same place instead of follow the track. I see under the mask my video plays normal, but mask stay always in the same place. Some can figure out how to solve this issue?
Thank you so much in advance! :smiley:
