.. "a few minutes" , don't think my connection is quite up to that speed but point taken , also I read back and realised you had a 2.8GB file already up currently not the full 6GB catalogue so that would probably be doable.
I'll have to check on a GMail account, fairly sure I don't have one but I'll check on that and PM you in the next day or two once I've at least got the game working. I'd be curious for a quick summary of what you've got installed though if that's cool, is it all just tracks and custom skins for cars or other stuff?
So far, I mostly have just been downloading tracks. Here is what I have so far.

An "Oval Track Pack" Not even sure what's in it yet.
Also, also, is the port forwarding mandatory for multiplayer to work correctly or more of a "do this if you have problems" solution?
It's mandatory.
