xspf to fla conversion is not possible, simply because .xspf file is a playlist and .fla file contains multimedia data. You have to convert multimedia files to other multimedia files, or perhaps do conversion between two playlist formats, otherwise it won't work.
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.
