This is a public forum. Here are users to help each others, if you need help from MAGIX itself you have to contact the support. Also NEVER post your serial number here, since everybody can see it.
As @Larry98 entirely correctly says, this is a public forum and confidential data like your serial number and computer ID should NEVER be posted. Hence, I have edited your post to remove this data.
Please use the Support button in the header of any forum page to contact Magix Sales.
