Oh I see, my pokemansion site suffered the same fate a few days ago and I fixed it myself. I wouldnt call it hacking since whoever did this wasnt really able to retrieve important site information from you.

The problem is with the folder /install and its contents. You need to delete it once installation is completed, since someone else could easily run the installer script and overwrite your config.php file with whatever information he/she desired.

So yeah, delete your folder /install from root directory, and edit config.php file to what it used to be. This should fix your problem.
