changing credit card info

I try to change my credit card info, but the page is blank when I click the bottom.

Hi,

Since we have recently changed payment processors, I would recommend downgrading your account back to a "Free" account first. 

1) Click on the Profile icon in the upper right.

2) Select "Account".

3) Select "Billing" from the left panel.

4) Select "Switch Plan" on the free account option.

This will cancel your current subscription and prevent our old payment processor for attempting to charge you further.  After you have downgraded and cancelled your account, upgrade back to the subscription you would like with your new card. 

If you have any further questions, let us know and we will be happy to help.
