Hi everyone in this thread,
Sorry to hear that the system is not working for you. Could you please give us more information so we can replicate the issue here.
What device are you using (PC, Mac, iPad, Android phone etc)?
What browser are you using?
When you say ‘nothing seems to be working’, what do you mean?
Can you see the little rectangular selection box?
Do any error messages appear?
If you send us more information then we will be able to resolve the issue.
