HHVM compatibility

Hi Thom, I am having a compatibility issue with HHVM, this is the error I get in HHVM error log:
\nFatal error: Switch statements may only contain one default: clause in /srv/www/polizzeperstranieri.it/htdocs/wordpress/wp-content/plugins/file-away/lib/cls/class.fileaway_admin.php on line 351

If I disable the File Away plugin all works fine.
Could you suggest a solution?

Thanks
Ivano
