Q: Updated to Yosemite, I have Aperture 2.1.4 which worked fine on Mavericks. It is now saying I can't use it on Yosemite. Any help?
Do I need to buy new version of Aperture just to make it work on Yosemite?

Yes. Only Aperture 3.6 is compatible with Yosemite. Upgrading from aperture 2 to Aperture 3 is a paid upgrade. You can buy the upgrade from the AppStore.
You have been lucky, that Aperture 2.1.4 worked well for you. There have been compatibility issues with Aperture 2.1.4 since MacOS X 10.7 Lion came out. The last compatibility update Aperture 2.1.4 was for MacOS X 10.6.8. Snow leopard is the last MacOS X version, that officially supports Aperture 2 well. Yosemite is the fourth MacOS X upgrade, since Aperture 2 has been replaced by Aperture 3 in February 2010.
Be sure to keep a backup of the Aperture library, before you upgrade. The upgrade will rebuild the library in a new format. See the Release Notes, i.e. the last paragraph, "A Note on Upgrading" Aperture 3.6 Release notes http://support.apple.com/kb/TS2518
