[Beta Release] Pwn Your Phone with Windows | Winpwn

[Baenor]

Hi guys.
I successfully pwned my iphone with this tool, but when building a custom ipsw, i can't access the built in source browser.

When attempting to refresh sources i get this dialog:

See the end of this message for details on invoking

If i click "continue" i can still build custom firmware, but I can't use installer or any installer packages.

Any ideas?

EDIT: It is now working after restarting my PC and disabling my firewall - I am unsure as to which of these things fixed it though.
