Somehow I have my paid subscription on the profile user 53240150 on my phone app with associated email shereeadmta@gmail.com which I am hoping to change to my main email i.e. hpnllc@gmail.com.  I have another one on my desk top and get emails but it was not set as a paid subscription with user 55242622.  It is associated with my email sheree.a.naquin@gmail.com.  I would like to get my desk top to work for the paid subscription profile.  How can I best achieve this?  Thanks!
