no workings for uptade activation code, i shared my solution for somebody have the same situation. you should use the runasdate.exe program for run new the etap 11.1 in one day don't expire, in my situation is 18 of april of 2014 and create a shortcut.

also, would you change the date of windows, but is more effort.
