Cannot Download Packs

[Luminex]

My problem has been that whenever I try to create an instance of Yogscast Complete Pack it always gets stuck at "Downloading Mods". It never gives an error message of any kind. I've seen the post about whitelisting domains, but as far as I can tell Windows Firewall doesn't have a section for whitelisting domains, but I made sure Java and the ATLauncher .exe were added to the program exceptions list. The only antivirus I have is Bitdefender Free, and I don't think it even has a firewall. I've also tried removing and doing fresh installs of Java (both 7 and 8) and ATLauncher. Nothing has helped.

Then I saw the post about debugging and downloaded the DebugExe.bat file and ran that. Maybe I'm just being paranoid, but just in case I'm gonna send link to the log as a PM to RyanTheAlmighty, as was suggested in the post.

I will say that what I found is that it always hangs on this line: "Connection opened to http://adam.nodeservers.net/containers/a...1.6.4].jar"

If anyone has any idea what this means and how I can fix it I would very much appreciate it. Thanks.

Edit: I should probably add that I'm on Windows 7 64 bit.
