Can't add BuddyPress language file in Codestyling Localization

Hi there,
I’ve never experienced this issue before:

I’m using Codestyling Localization for translations and I can’t seem to be able to add language to BuddyPress plugin.

I get this error: “You do not have the permission to create the file”.

I am the administrator so have full access (and can add language files for any other plugin in Codestyling).

As far as I can read this has got something to do with theme compatibility.

Do you know how to make it work?

Cheers!
