Favourite directory loss


I use Mp3tag with my own Favourite Directory ("start from here" activated) for a certain time without any problems. Now I added one tagfield and saved my configuration.
Since that time the programm starts allways with C:\Programme\Mp3tag as the Favorite Directory. In options my Favorite Directory is still configured.
Even if I change the actual directory after the next start the programm starts with C:\Programme\Mp3tag

How can I get to my own startdirectory

In the German forum noone could give me an answer so I hope you understand my poor English
