Some days ago I ahve successfully installed and activated Studio 2015. After some adaptations in the ribbon and the letter size of source and target text as well as the preparation of new projects , I closed Studio. When I re-open Studio 2015, and try to open any file independently from which project. I get the message "The specified item is already part of a command bar". The programm stays in the file window, If I try to get anywhere else, appear other error messages, but I can't leave the file window.
Does anybody know the solution?
Kind regards
Armin
