Windows .exe Direwolf20 1.6.4. Error

Hello guys. I just downloaded Direwolf20 1.6.4. pack and when I hit Launch button, the launcher freeze, button remains grey and I get this in the console:

Am I doing something wrong?

Thank you in advance! Best regards,

After a small bit of my own testing I found that deleting every file in the folder with the launcher BUT NOT FTB ITSELF (BEWARE THIS DELETES YOUR SAVES!) as well as setting the download server from automatic to Nottingham allowed me to launch.
