Hello every body: 

  I did buy The SolidWorks connected last week and it is student version to practice and learn about it.

I did open one of my assembly which I have done on my SolidWorks 2021 and now I need to open that file and I can not because it has been upgated to version 2024 by the SolidWorks connected.How can I fix this problem? Do I have to redo the hole assembly and may be the all the parts
