I'm sorry - I don't know much on the topic of fuzzy ontologies.  You 
might be interested in reading a presentation from the 2009 Protege 
Conference entitled "Fuzzy Protege for Fuzzy Ontology Models":

If you've tried opening an ontology written in a format that Protege 
doesn't support, this is likely the reason.  Although, it's hard to say 
w/out knowing what file you tried to open and w/out seeing the error 
messages from the Protege console window.

The W3C has a document on their website "OWL 2 Web Ontology Language: 
New Features and Rationale", which addresses your question:
