While we can certainly take a look at this, it nees to be advised first of all that whether your license is showing valid or not on your dashboard, it does not in any way at all affect the functionality of your platform, and the only person who would see this is a member of admin. These issues tend to occur when your server cannot contact the licensing server for some reason.
With regard the message there, I would need more context as to what that says there, and where you got the message. Unfortunately as the issue is no longer present there isnt anything there to investigate. If you get messages like that at any point, please do let us know first and then we can take a look to see what the cause is for you.
I did notice on logging into your site you are a few versions behind. Please update those to the latest release. Also, you should address the items in the support area under the mysql area. These can cause slowdown on your system, and cause the database to lock meaning things cannot be read or written at that time. It may well be this that is causing you other issues.
