New edition needs updating > Likes and Comments

I recently unpublished the first edition of my book. And I have now republished a second edition. I also got this message on my page "This item does not meet our catalog guidelines and can no longer be rated or reviewed. Learn More" Can someone please help me get my page up and running again. There will be a new ISBN for the second edition etc. Let me know what I need to do. Thanks so much.
