This is how I downloaded Active X and what happened with me.
First I downloaded Active X by the site asking me to, at the top.
I knew before, that downloading Active X by site wouldn't work but I still downloaded it. Then I downloaded Active X manually.
So what I'm trying to say is to download Active X when the site asks you to, then download Active X manually. Also try to reinstall Active X again and after you think it is finished wait for about a minute because maybe it's still not finished.
The problem why I couldn't get Infinity to work was because of firewall. You've tried everything in my guides right? Firewall, trusted sites, suggestions, etc.
Also can you explain your problem again because it you said that you've gotten past Active X and now you're not? Yeah I'm confused
