I`m having a hard time trying to save files to older versions. I would like to know how to save my Archicad`s file version 25.0.4013. to version 25.0.3002.

Have a read of this article
you need to backsave to 24 and then open in the original earlier version of 25.

FYI: This was kind of a one time thing that the file format changed within a single version (AC25). This was because new features were implemented that required file format change.
With any other versions you do not have this issue.
