Technic Won't Download My Custom 1.6.2 Modpack

[Darkweaver66]

Launcher Version: 1.6.2

Operating System: Windows 7 Home Premium 64-bit

Java Version: Version 7 Update 45

Antivirus Program: Microsoft Security Essentials

Description of Problem:

When I go to download the Modpack I have just setup (which as far as I am aware has been done correctly, though I have probably missed something) It shows a very brief download bar that lasts around 1 second, then vanishes and goes no further. there is no error message but the error report attached shows that it has hit a wall. Can anyone help?
