you're trying to save the removed pages or the original pdf but with those pages removed?
in the future, to find the best place to post your message, use the list here, https://community.adobe.com/
p.s. i don't think the adobe website, and forums in particular, are easy to navigate, so don't spend a lot of time searching that forum list. do your best and we'll move the post if it helps you get responses.
