Problem with Creation Kit: Can't handle multiple masters

[st0815]

Hi, I'm trying to save a mod plugin file from SE form to LE form. But befor I can even open it I always get "Invalid file selection". The file has Skyrim, Update, DB and some others listed as masters. The CK warning is "multiple masters detectet to load" abortet. Although I have none of the listed and only my mod plugin is set as active file.

What can I do to get this to work?
