sorry jyoti i was being anti godaddy. their way of doing things is quite different from most everyone else in the business IMO and i have seen their user panel and it is not user friendly at all. Ross should be back on tomorrow and hopefully he may have some good news for you.
I already told Jyoti, that this problem is related to the hosting provider, you need to contact support team and find out why your account doesn't have such permissions.
