Hi, since a few days now I have a problem with Itunes and the Software Update. With Itunes it's saying : "iTunes cannot connect to Store Purchases. If you have any firewall software, make sure it has been set to allow communication on port 443." Even if I desactivate the firewall With the software update it's saying that an error has occured and it has been impossible to connect to the Software Update server. It's been a few days now and still the same problem. Didn't change anything in the meantime, the software update worked well before. Anyone can help me please?
