Hiiii

Thanks for approaching us. Since the exam is scheduled in a week a lot of  candidates would be trying to download the admit card at the same time, and so the interface might be facing some technical issues. Many candidates are facing the same problem. I would suggest you to wait until the end of the day and try downloading your admit card again.
Even If issues still persist, please reach out to them and mail them your issue at mat@aima.in or call them at 011-47673000.

All the best
