I am not the technically savy guy, but others will surely ask for more information before they can help you. what does not work? can you not log in to ironclad online? can you not host games? can you not join them? is it just slow? what kind of error message, if any, is displayed?
just write everything that you think has to do with the problem and might help others solve it. that way you get better and faster answers. sorry if I cannot be more helpful.
