All of this information was provided in my initial post but I'll put it on the template anyway.
The following is the basic SRT
Your board's URL: http://localhost/phpBB3
(not yet set up to a domain name)
Version of phpBB3: phpBB-3.0.0
Was this a fresh install or a(n) update/upgrade/conversion (please be specific)? this is a fresh install, but this might matter: "When I first downloaded them and attempted to set up things on my server (I'm using Apache 2.2) it worked fine, I got all the way to the table creation stage of install where I would get an error with the 'syntax' creating them- which I figured out was because I'd been selecting MSSQL instead of MySql 5"
Version of PHP used: PHP 5.2.5
Database and version used: MySQL 5.0
Was this an install through your host? No, extracted zip file and copied the folder and all files inside to the document root of my server.
MODs you have installed: None, logically. phpbb3 isn't installed.
When the problem started: Upon attempting installation.
