BreezeBrowser Pro does work with Olympus ORF files but my guess is that support for your particular model is not in the version of BBPro you're using.
I don't know if this list is comprehensive but it appears that no Olympus cameras have been added since December 6, 2010: http://www.breezesys.com/BreezeBrowser/bbpro_release_history.htm
EDIT: I downloaded sample ORF files for the EP-1 and EP-2 from this site: http://www.focus-numerique.com and was able to convert the EP-1 file using BBPro v188.8.131.52 ... it refused to process the EP-2 file. This was the result...
I see you asked the same question on BreezeBrowser's forum so I don't get the point of posting it here when the developer answers questions directly on his forum.
