Please be aware these are public forums for user to user assistance. They are not a link to Magix Support. Hence you should never post confidential information, like your serial number! Hence, I have removed it from your post.
I rather suspect this question is one which you will need to raise with Technical Support but you will need an existing Magix registration to access that page. An alternative page is here.
This is essentially a duplicate post. Again, please do not do this! My advice is the same as posted in your other thread, and as advised to the OP in this thread, contact Magix.
