Problem with trees

[Rav]

Hi guys,
I got a problem with rendering trees. When I add a tree to project in autocad it shows just as a white stick, and when I render It nothing shows up. I got win7 64bit, autocad 2014. Can anybody help me out? I've even tryied on other computer with win8 and autocad 2015, same problem occured. Is it because of broken trees files? I don't think so, cause I have downloaded it again from this forum. Soon there will be project rush :P at my university so I need your help.
Thank you in advance,

Best bet is to include a simple drawing showing the problem.
