Aakash Institute — I am complaining about the problem faced in aakash itutor

I have purchased aakash itutor medical platinum subscription for 2 years . In the beginning it was working quite well but now when I use to play the video it says that please insert sd card although I have inserted sd card but video can't be played . And now it's high time for the neet preperation as the date has been announced but I am not able to study due to the problem.And i have also emailed them and told about my problem but the problem is not still resolved yet.
