Newbie: Unable to log onto any discovery server

[Goomba]

Absolutely no idea why do you have this problem, and pretty much the only thing we can advise is a complete reinstall, oh, and you are asked twice for the directory during the installation, 1st is the FL directory, 2nd is Discovery FL you want to install to, make sure you install disco into the vanilla FL folder.

i left everything as was suggested by the installation files....i did not pay attention of where exactly everything was installed. does the fact that im able to start it up and play in single player suggest i have it installed correctly?
I had it installed then reinstalled it after my initial attempts failed...

EDIT: also - im running it on Windows 7 - dont know if there are known issues with it...
