Are my posts safe?

So it is safe to wipe the rest of my wordpress installation?

Alright. What about image/file uploads that I still need?

The thing is — I really, really messed up my access to wp-admin by changing the link of the blog. We are updating for my website’s second anniversary, and now I can’t access the admincp.

I was trying to make it to where visitors of the site couldn’t see the blog so I could work on it in the background… but now I royally messed up.
