Ahh! Modified config.local.php now site says not installed

I think I had a botched upgrade from 2.1.2 to 2.1.4 and so when I was looking at comparing the config.local.php and config.php files from my site and distribution. I removed several lines from one of those files, don’t remember which and now my cart says it’s not installed.

If I do the installation again, it will overwrite my entire database. What do I do?

Okay, well, I reinstalled the cart using a different database, then I put the right database information in and the cart is online now.
