Translate enroled into the course in Jomsocial activity

Hello. I use Joomdle 0.92, joomla 3.1.5 and jomsocial 3.0.4. I tried to translate string"enroled into the course" to my language but not successfully. I changed string COM_JOOMDLE_USER_ENROLED_INTO_THE_COURSE in en-GB.com_joomdle.ini, also changed string in ws.xmlrpc.php but it's not working. Please tell me how to I translate it. Thank you

This works fine for other languages, so I don't know what your problem may be.
Are other strings working fine? Double-check that there are no errors in the lang file.

Thank you for your fast reply. Now it works fine for me. When new user enroled, it show in my language. But when Users enroled to course. This user is not added to Jomsocial course group. How can i fix it?

It should work if you enabled the group option in moodle (I just tested a nd it works fine for me)
