I have the steam version and a separate conquerers version of the game but voobly is using my steam version which is giving issues. I need help connecting to my AOC game instead, rather than the steam one.

hi
if you use the steam version here, you will need this patch: [You must login to view link]

pick the lobby you want to play in, then click it and you will see this: [You must login to view link]
click the button that says "choose" and browse to the EXE of the game you want to play: [You must login to view link]
click open, then open link.
see if that helps.

I'm in the lobby page but I'm unable to get the launch application window.

hi
odd
try joining voobly through the web site: http://www.voobly.com/
