Looks like something is blocking your from downloading. Check your antivirus or firewall.

i dont exactly know what to enable/disable in my firewall can you help me?

 

[UniZero]

If you are using the windows firewall it should be fine but if not then you will need to check your one. Google is your friend.

If it is the windows firewall you use that does not block outgoing connections. It is most likely either your anvtivirus or some other security software that is stopping you from downloading the pack.
