How do I retrieve my data from last year's Reckon Personal Plus 2023 backups onto my 2024 program?

I am extremely frustrated and need help from anyone who knows Personal Plus. I have bought the 2024 Reckon Personal Plus version but when I installed it and opened it up there was none my previous data. I now want to retrieve the data from my backups on my PC but cannot see how to do it.

Can anyone help me please? I rang Reckon but they said there is no technical support available for Personal Plus users.
