I have CS6 and Windows 7. If I want to test for updates the application manager can't get contact to the server. It refers to maybe a firewall. But as far as I know (I'm no expert) I haven't installed a firewall. What might be the reason? It worked fine for some years and as fas as I remember I didn't change any setting. I'm using Avira as virus protector. Any advice understandable for non native English speakers and not very experienced PC user?
