Hi captgadget ,
May be you can then try using different web browser to open My Cloud.com
As this is confusing but if you open My Cloud.com, it will take you to the page where it will ask you to Sign in or to create an account. Because , actually you are on the My Cloud Home Login page but if you just check on the top right corner of the page , you will get two options My Cloud Home| My Cloud. Just need to click on My Cloud and then you will be able to login to My Cloud.com.
