I met with this error before.
What is the unclean file? TagEditor?
1. Bad source text e.g. prohibited markings, trace changes.
2. Source text is used by the other program.
1. To eliminate bad markings, save source as text (e.g. using Notepad). And recreate source text again (e.g. *.doc, *.html, *.xml)
3. Clean the file.
