Sorry for not having been on in a little bit..
I first downloaded the phpBB3 to my system where I extracted it with winRAR.. I tried to upload the folder, but I couldn't figure out how to upload an entire folder (it just let me upload the files one by one) since I'm not that used to a hosting site like this (for my last site, everything was done through an FTP, which I tried using this time around, but the files just wouldn't upload properly) so I decided to upload the ziped file and extract it with the cp extraction tool. I followed the instructions given to me from the phpbb.com site, but I couldn't get to the install page. (I hope this gives more info into my problem. For now, I will try using Fantastico and see where things go from there)
