Event fresh trial install throws "Evaluation has expired!"

Regarding Even a new build, a new app, with a fresh NuGet installation of “dhtmlx-scheduler for asp.net” throws Evaluation has expired!.
I tried on 2 different PC with separate Visual Studio installed (2012/2010)
Why? I suppose this happened due to the last update or smg?

Basically Uninstalling from NuGet and adding reference + scripts manually did solved it! Later on NuGet installation again worked! Things happens!
All ok!
