Operating System: Windows 7 Pro x64

Java Version: java 7 update 9 (build 1.7.0_09-b05)

Antivirus Program: Microsoft Security Essentials

Description of Problem:

I have a similar issue, where I can select and add modpacks, but their titles and versions usually just hang on the loading message or for versions just show recommened build, and not veersion numbers.

I think this is also effecting people being able to connect to servers, as I don't think they are getting updates in their launcher, and this would explain why on my server, so many people were joining, but were getting unloaded as soon as they joined.
