I had been logged in to this forum in two computers, both in my house, same email address and settings. I got an iPad and now I can only get into one computer and the iPad. Coincidence? I changed my password and did the same maneuvers in all three devices but one just won't let me in. What to do? I'm afraid to tweak too much because I know there was a problem with Comcast users a while ago. Don't want to revisit that.
