It is not actually possible to convert MP3 to SES, because a *.ses file contains meta data for a project, not the actual audio data. You can import MP3 to Adobe Audition and create a new project. That will probably generate a *.ses file as well.
This conversion entry was verified by us and conversion was flagged as wrong or not possible.
Usually this happens when the conversion would try to convert different types of data between each other, such as audio to image, or it is not possible because incompatibility between programs, caused by closed file formats, very limited support etc.
If you find entry that you feel is flagged as bad wrongly, please tell us in the discussion below with as much as information as possible so we can fix it.
