Today I have updated my IDEA 12 EAP installation via automatic update, and after restart it told me that I have to enter the key and that my evaluation has expired! But it is EAP, why it did so? Also, when I refused to enter the key (I don't have one, of course, it is impossible to buy upgrade yet), it said that it will shut down in 30 minutes. The about screen then showed that my evaluation ended at January 6, 2012! Then it really closed after 30 minutes. What should I do with this problem? I thought that EAP evaluation will be at least 30 days after release.
