Insufficient privileges as an administrator? Is that possible????

Insufficient privileges as an administrator? Is that possible????

I have been having trouble using my ZOHO account from home on a different computer. Often it would give a message that I do not have sufficient privileges when that is not the case as I am administrator to the account. 

I also have been unable to add the parent company to a company and have tried it several times yesterday and even today but unable to do it saying unable to process your request; Click to go back. 

Is there some problem at your end or just what I am doing??
Thanks
