Language Issues in Group Forum only

Hi,

I had an issue with my orca forum not compiling languages. I was recieving this error message:

[L[Language files compilation have been failed]]

I followed this guide as someone suggested on the forum:

http://www.boonex.com/trac/orca/wiki/GenOrcaTshooter#WhenaccessingOrcaIgeterrorWarning:fopen...orcaconfparams.conffunction.fopen:failedtoopenstream

and it worked.

However, a few days ago I noticed the group forums were completely broken - none of the ajax elements were loading and as such, people couldn't add new topics/posts etc.

I've just established this is due to the files I deleted as suggested in the guide above. So I copied the deleted files back in, the group forums came back to life BUT I get the same error when trying to compile the group forum: [L[Language files compilation have been failed]].

How can I compile the group forums?

Nevermind.

I just ran through that guide again, but this time deleted the files suggested under groups>orca rather than just the orca folder.
