After changing my username and password for the database (and updating the wp-config again), the blog is now showing up! It doesn’t have any of the old database info (all posts are lost). I was able to find a button for “Import” within the Admin of the blog, but when I tried to upload my .sql file that I exported from the database, it gave me the following message:
“Please upload a valid WXR (WordPress eXtended RSS) export file.”
