Q: After upgrading to Pages 5.6 on Yosemite I can't find any documents on my mac?

Upgraded Pages to 5.6 (2553) on Yosemite 10.10.5 last night I can't find any documents on my mac. Though Pages will open a document off an external. Is it not reading the version of the documents created in the old Pages version or are the documents actually gone?

Any Ideas?

Thanks!
