JetBrains released a license enforcement in their latest products released this week that now blocks previous license servers from working. This did not take affect until today. More info can be found here:

You will now receive an error attempting to obtain a license stating that the server is outdated and cannot issue a license.

Work around for now, block this in hosts file:
Code:
0.0.0.0 account.jetbrains.com
Get key from:
Code:
http://idea.lanyus.com/getkey
This unlocks all of the 2018.2 products from what I saw.
(If you can afford to buy the real thing etc. support the devs when you can.)
