Can`t load older projects after Synthmaster reinstall

[yhimself]

Hi, i had to reformat my computer and reinstall my DAW and all vsts, but now when i open older projects all the Synthmasters inside them are reset to init patches.

I use FL Studio 12.3
I remember i used Synthmaster 2.8 before, and i installed the newest one now wich is 2.8.4 i think.

EDIT: My friend who i collab with is having the exact same problem with the same setup.

Any tips on how to fix this is much appreciated as i really want to be able to open all my projects again.

Thank you
