Assuming you bought VPX very recently you need to email infoservice@magix.net giving full details of your order (date of purchase, invoice number etc.) and ask for a refund.
If you are used to Movie Studio 17 or earlier than this was a Vegas product which was discontinued by the Vegas Creative Software.
The new Magix Movie Studio is very similar to Video Pro X without the extra tools, needed for professionals producing video commercially or for broadcast.
To get a refund email Magix at infoservice@magix.net
