Hoping someone has a solution for this problem, I have like .6 BTC stuck in there :S
Does it work if you temporarily disable the (windows) firewall? Do you have any other software that might cause this?
Turned it off and still the same issue :/
I don't think I have any other Anti Virus system etc that would stop it, this only occurred recently and I've not made any downloads/changes at all.
Was working fine for 2 months, but idk what's going on now :S
