I purchased Movie Studio 17.0 Platinum yesterday with my primary email address. Then when it installed today it asked me for my login and I used my secondary email address for that login. Now, when I open the application, it says it is registered to my primary email address. However, when I login to my Magix account online, it says it is registered to my secondary address. This makes it so that whenever I try to edit anything in the program I get an error code 24. It tells me to contact Magix directly but I have no idea how to get to them. Hopefully this works. Thanks.
