Unity 5 (bug?) trial version

Hi, I wanted to know if this is a feature or a bug and if it is a bug, how do i get rid of it?

I developed a small benchmark tool in Unity 5 for a client of mine. It is the first application I ever made within Unity 5 and i’m using Unity 5 personal edition.

I noticed a little piece of text in the right bottom corner displaying “trial version”. I thought that the personal edition only locked the splash screen. What do you guys know about this?

It is worth mentioning that I used trial versions of Unity 3 and 4 pro in the past.

Found the problem, it was the index-local.xml file, apparently it did not get renewed with the new Unity 5 installation, simply deleted it and the Unity_v5.x.ulf file. This triggered the re-activation of the personal edition and thus creating a fresh index-local.xml file. It removed the trial version.
