Can you send us the file "msms.txt"?
The first line of that text file typically has several column names beginning with "Raw file".
If you are getting an error saying that "Raw file" cannot be found, it might mean that none of the expected column names cannot be found in that file, or it might mean that some other text has been inserted at the beginning of the file which is confusing BiblioSpec.
If "msms.txt" is less than 50MB you can attach it to this support request.
