I'll try to clarify.
I installed Freespace 2 Retail from the CDs. I downloaded and installed Patch 1.2.
I then downloaded the windows Freespace SCP installer. I downloaded everything else through there - the whole 3.6.9 ... uhm.. everything.
I followed the instructions, made my account on FS2DNET or whatever it is called. I logged on by following the instructions (Creating a multi character, then under PXO entering in my FS2DNET login/password) and I connected.
I just found no games up last night. At all.
Yes I did forward my ports.
