The address for sending funds will be issued to you as soon as you click-Exchange.
That didn't happen...
- It gets stuck in a page that says "CARREGANDO" which I believe means loading (checking the source code leads to the error that stompix posted).This did not happen because your exchange amount is too small. I would advise you to increase the number of coins you want to exchange to 0.00035-0.0004 in bitcoin equivalent.
