Starting Studio 2014 Starter version...error message...had previously installed Trial version of Studio 2014...license apparently no longer works

Hi, I get a error message when opening Studio 2014.  I had downloaded the trial version before buying and getting a license for the 'Starter' version.  Now I can't open the program at all. How can I reinstall the 'Starter' version?  Here is a copy of the error message (in German).  Just mentions an error when calling up the license and allows me to either deactivate it, or continue.  When I push the continue button, nothing else happens. 

So I now cannot use the program at all.
