I think the auto installer has a bug, because i deletd the files off my wamp bymistake, and when I tried to reinstall nwe, faced the problem.
I noticed two things:
1) The license page has some default license number being written even when I input my number in the installation process.
2) The db.php file is nit having any license number written at all it just has a - there.
Maybe the autoinstaller is not writting the license numbers properly.
Oh and mine stopped working again, gotto try and fix it :/
