Accenture — Regarding my tasks completion

I have been assigned a task by Accenture to complete tasks on uploading documents and details. I received the email day before yesterday and I need to complete till tomorrow. I opened the link they provided day before yesterday and completed a few tasks but when I opened 'my tasks' yesterday the page was loading and not responding. I have been trying since morning but the page 'my tasks' isn't responding. I would be grateful if you could give me a solution to this problem.
