[Technic logo freezes in middle of screen and doesn't open]

I uninstalled AVG and it opened but when I tried to login it said update failed, so I closed it and tried to open it again and it is doing the same thing.

[Technic logo freezes in middle of screen and doesn't open]

Launcher Version: 7.2

Operating System: Windows Ultimate x64 bit

Java Version: Java 7 x64 bit

Antivirus Program: AVG 2013

Description of Problem:

I open the Technic launcher, the download bar comes up, downloads the files then when the logo pops up in the middle of the screen it freezes and just stays there. The only way I can get the logo to go away is if I close it down in task manager. I've tried disabling my firewall and it still doesn't work.
