Hi   I installed Crashplan on my iMac this week but I am unable to get it to connect with the internet so it won't back up. Crashplan support suggested deleting the app and reinstalling, which I did but it still does not connect with the network.   As far as I know I have no network issues. Everything else is happily talking to the internet. I don't have the firewall turned on either.    I'm now at a bit of a loss over this. Is there something in Crashplan...
