When did you buy the license?

According to the message your license expired on 10/jun/2017 so you're not allowed to use a version newer than that date

Thanks Charlie. Yes, I have tried on June, and I but the licence this year.
I delete my old Jira installation and I run a new installation.
But the problem persists. Where am I wrong in your opinion? Thanks so much!

You need to give it the new licence key.

If you've bought a licence this year, then you can get the key for it from my.atlassian.com and paste it into the box you've part redacted
