I cannot access my product pages at when I try, I get a "system down for maintenance" message.Ĭould that be the issue: at startup, Mathematica checks on-line against what's registered at Wolfram but, since their site is down, it cannot verify the key?Īnother possibility: I had to reinstall OS X 10.11.3 on my Mac because of a bug Apple unwittingly introduced in a "silent" automatic security update.

When I typed it in, I was told it was for 10.3, not 10.3.1. Today my unexpired Activation Key for Mathematica 10.3.1 suddenly stopped working When I opened Mathematica, I got a "Wolfram Product Activation" pop-up asking for the key.
