Running FCPX 10.5.1 Need to repurpose old projects but can't convert

I have been editing on FCP for seven years. Created projects in 2014 and set aside. I need to repurpose them and found that I missed the window (10.2.x) for converting. Can I get a version older than 10.3? 

2014 projects should be in 10.1, in the library format. I guess you were still using the pre-10.1 version. What computer are you using? It'll have to be running an old OS to run 10.2.3. 

Thanks, Tom. I fired up my old MACBook Pro (2008), wiped it and loaded 10.11. El Capitan. I went to load FCPX and it automatically loaded 10.3.4. It gave no option. Where would you recommend I find something < 10.3?

You need 10.2.3. I think it will run on El Capitan, but I can't test that far back any longer. Contact me through my website. Google should find it.
