Help please! Old blog exists but won't import/log-in

Hello,

I am trying to import my old blog (https://www.delightfullydysfunctional.com/blog) into my new blog. I installed WP on the main page of https://www.delightfullydysfunctional.com and log-in. There are no posts except for the new, initial WP one.

I try to log into my old blog (www.delightfullydysfunctional.com/blog) but once I login (same login info), it takes me to the new setup with just the single WP post. All of my old entries are visible on my old blog, but when I click the “read more” tab below each, it says “404 error, page cannot be found.”

I don’t know what to do to rescue all of my old entries and put them on the new, mainpage.

Please HELP!!! I think I may have screwed something up bigtime. Is my old blog lost forever, or is there something I can do to move it onto the new server/mainpage (www.delightfullydysfunctional.com)

Any help you could give me would be HUGELY appreciated.
