I just bought a new IMac and signed up to CC. I have no firewall and no problem with internet connection. Browser is Safari. I've downloaded Illustrator with no problem, then downloaded Photoshop. PS seems to be working OK, but when it finished downloading, there was a message to say that a patch had failed to download. I've tried to update it several times since, both yesterday and today, but keep getting the following message - 'Update Failed. Unable to reach Adobe servers. Please check your internet connectivity, firewall settings, and then try again.' Is this patch important? Am I likely to have a continuing problem downloading updates? If so, what do I do about it? (I would really appreciate simple answers if possible, I'm not very technically minded and easily confused!). Thanks.
