[Doggiebox] Problems with drumkits prior to 1.2

Hi, I tried the following with DB 1.2: - opened the Hemberger Kit - "saved as" Hemberger.dbkit in a new folder - a subfolder is created name Hemberger.dbkit which includes a Hemberger.dbkit file and a subfolder called Sounds which includes all the AIFF Files for the particular drums - opened a Song created in 1.1 / or any other song created with 1.2 - try to apply the new Hemberger kit (the file open box does not see the Hemberger.dbkit file although it's there) - reopened the Hemberger.dbkit file - all the drums had no AIFF file assigned (could not be found) - tried to assign the AIFF files manually - Message "unable to save document" How to proceed?
