How do get LanguageTool to work?

I am using Ubuntu 12.04 and LibreOffice 3.5

I have tried loading LanguageTool a few times but I can’t get it to load. I keep getting error messages and the extension wont work.

I download the extension, then go into libreoffice and go to extension manager, add, select the oxt file and then it gives me an error. When I open libreoffice again the extension is in the extensions menu (greyed out) and gives the option to enable, but when I select that again nothing, just an error message.

Thank you for any help.

What error message(s)?
