Q: I have mountain lion (10.8) and i have a loop telling me that I can't update iPhoto or Mindnode Life without going to Comcast.net.  This is an endless loop.  Any suggestions?  Comcast, of course, was useless; they suggested rebooting and that didn't work.

I have a message telling me that iPhoto and MindNode application updates are available to me, EXCEPT I must sign into comcast.net first and update there.  This is a continuous loop; same statement; same nonethingness.  any suggestions?  Comcast technical support suggested I re-boot.  I am still in a continuous loop.
