Ok, I've studied Latin in high school but it was a long time ago :-) "Conentur" is the third-person plural present subjunctive of "conor" (to attempt, try). "Se invito" is the so-called "ablative absolute" (here using a pronoun plus an adjective). It can be translated as "against his will", or more literally as "he (being) unwilling". Hope it helps, tano
