Hello, I just bought Mathematica 10.0.1 on 12-5-2014 at 11pm. I understand there is an upgrade which has bug fixes. How do I upgrade to 10.0.2? I can't find any commands in the menu to upgrade. My User Portal only offers 10.0.1.
Although I have been using computers for a long time, I am a new user to Mathematica. I did notice, when I use the menu or enter different formulas, my CPU jumps to and stays at 12%. I have a 4 core i7 and this almost never happened before I installed Mathematica tonight. I can see from the Windows 7-64 bit Task Manager that it is Mathematica which is doing this. The only way to stop my CPU from staying at 12% is to completely exit Mathematica 10 and return. So far, I am not very impressed with Mathematica 10.
