You completely disenfranchised many users. MS18 is NOT the same product and does NOT have the same features as previous versions. You should have notified customers of this prior to having us pay the $50 to upgrade. We should be upgraded to Vegas Pro since you have scaled back on the features of MS18.
Welcome to the Magix user to user forums, so not a contact for any Magix staff and we are not disenfranchising anyone!
Movie Studio 18 is a new (to Vegas users) product, a rebadged version of Magix Movie Edit Pro. This has been stated by Magix, although admittedly not very clearly!
Please see this forum post by a member of Magix staff, which sets out clearly your options.
I believe the first offer on that page has now been redacted as Vegas Edit 19 has now been released. Offer one now only takes you to a subscription based offer. I stand corrected. There is still an upgrade option.
