If you’re running IntelliJ IDEA 15 Ultimate, you can sometimes see a confusing message in the Updates dialog, saying that you can evaluate the new version for 30 days, or buy a license key or upgrade online–regardless to the active state of your subscription.
We apologize for this, and promise to fix it in the minor update that we’ll be releasing within several days. Meanwhile, simply ignore this message. Thanks for your patience!
