Getting 'Couldn't load XLIFF module' when trying to export as XLIFF

Hello!

I've now tried with the latest Stbale XLIFF-module and the latest Dev on, and I've tried with the latest Stable Translation managemet module and the latest Dev, but each time I try and export as XLIFF, I get a 'Couldn't load XLIFF module'

Please, anyone got any cool ideas?
