Bug in translation

I translate the Videochat (Messenger) section and then it appears: "btnsendfile",  "btnVideos",  "btnPhotos" etc...

Instead of "enviar archivo" "videos" and "fotos"  (In spanish)

Please, fix it

Hi

can you provide me with your test site url? I will let you know where the problem could be.

mi URL is: foro.x10hosting.com

it's where it's installed for trying the script

everything is all right installed because... I translated the small chat, the big chat, the boards, and the IM is not working as it should do.

The translation files are all moreless the same, so I don't understand what I have done wrong
