FaceTime suddenly stopped working
When I first set up FaceTime on this Mavericks install (first time ever using FaceTime, I'm not sure if this is important) it worked fine for a while, but has recently just stopped working altogether. The Apple troubleshooting page suggests going into FaceTime preferences and fixing some options, but the option to get at FaceTime preferences is greyed out for me.
When I log into FaceTime, it asks for my username and password, then asks which accounts I would like to use with FaceTime (I have two options: my @icloud.com address, and the address I use as my apple id. I've tried leaving only one of them selected to no avail). When I click next after making sure one or both of my accounts is set ti sign in, FaceTime says "Verifying" for a while before going back to the username/password step with no error message whatsoever.
I'm running Mavericks with all of the latest updates installed on a late 2009 MBP with a 3.6 Ghz Core 2 Duo with 4 gigs of ram in case system specs are important.
