When you upgrade to Premium, it is confusing when you try to put in your credit card information. For the expiration date, if you put your cursor on the drop down arrow, it is inactive. You have to position the cursor left of the arrow, but within the box. For the year of expiration, the year you have chosen from the drop down does not appear in the box, and you only see the first 3 numbers of the year. I was able to sign up for Premium today, but had given up trying to enter my payment info last time I made the attempt. Thanks for your help.
