Not able to download free Catch Updater

I log into my account here and when I go to download the free "Catch Updater" on the checkout page I get the message that I need to login in order to download it even though I already am logged in. So I click on the "My Account" which should take me to my account since I'm already logged in but I get taken to a login page. So I try to login with the correct email and password and I get an error code that says I'm using the wrong credentials even though I am not. So I try several times and I am unable to login in order to download the plugin. Here's a screen grab from within my account when I'm logged so you can see I actually am able to login: Screen grab of the Checkout page: Error message I get after entering my correct information and it says I need to login even though I was before I came to the Checkout page: Screen grab of the error message I get after I try to login with the correct username and password: After this happens and I can't login on this page, I to another page on the site and I'm logged in. Can you tell me how I can login on the Checkout page in order for me to be able to download the Catch Updater plugin? Thanks.
