Confidential data, like order or serial numbers, should never be posted here. Hence, I have changed the title of your thread.
Please state exactly which version of Photostory you have purchased, whether it is Photostory deluxe 2026 or Photostory deluxe 2026 Plus. Also, in what currency did you pay? According to this web page the upgrade price for deluxe 2026 is $24.99 and for deluxe 2026 Plus is $59.99. So, it seems you have not purchased the Plus version. What does the confirmation email you would have received after purchase say?
If you have accidentally purchased the "wrong" version please email infoservice@magix.net with full details of your purchase, request a refund and then buy the version you want.
Further to what Jeff indicated, "Plus" is just Photostory Deluxe "plus" Photo Manager and possibly PanoramaStudio 4 Lite. I'm not sure about PanoramaStudio, but I received it with Photostory Deluxe 2026.
While Photo Manager is an excellent program, it's quite old (2015) and some of the features no longer work. For example, an album created in Photo Manager (xxx.alb) can no longer be opened in Photostory.
The program definitely needs upgrading, but, I still use it for some of its features.
You may want to try it out first to determine if you want or can use it.
