How can we downgrade Pages 5.5 to Pages 09?
I just updated my rMBP to 10.10.3 from 10.9.5. In doing so, I enabled automatic updates in the App Store. Unknowingly, I replaced my Pages 09 with the new Pages and I've lost a great deal of functionality that I depend on for document and manual creation.
How do I downgrade to Pages '09 (4.5.3??)?
Must I revert back to 10.9.5?
Mac Pro, OS X Yosemite (10.10.3)
