For those who experience the same problem, here is how i fixed it: After a couple of try and errors, I found out the problem was about creating an activity in the create project wizard. If you simply deselect the create activity button at the 2nd step of the wizard, it creates the project succesfully. After that, you can add a new activity to your project easily
