Been getting Host Wait Time after completing the jigsaw captcha.
No successful download what so ever so far.
Also, after waiting for 1.30hrs (during the Host Wait Time period) other downloads never starts nor did the jigsaw captcha eve appear. The next download will appear either Host Wait Time or Temporary Unavailable (links are working fine on web browser)
