10.2.0 won't update to 10.2.1

I updated and worked on a project and library files via HDD at my office (iMac) and now I'm home wanting to finish the project on my macbook Pro. Problem is

NO FCPX update appears in app store

and when I go to purchases, I get the error:

my FCPX is version 10.2, and will not open my Library files from HDD because I get this issue:

My questions is, other than deleting and reinstalling 10.2 (not a good option, I have grading and filters installed) what can I do to update to 10.2.1?

Is there a direct link to download so I can force instal?

Any help would be appreciated.
