Feral Heart

I have several meshes, mostly tree, rock and some nobplant meshes that disappear when I log in and check out my maps on my characters. They show up perfectly fine when i'm in map maker, but are gone afterwards. They are not ingame meshes that came with the game download, I had downloaded them from mediafire from people on this site who made them.
Does anyone know how to solve this?

Name: Kira
Age: Young Lioness
Has Pride
Mate: none, but is open
Feral Hearts Username: Nekolover
Personality: often alone, mostly because all the lions in her pride ignore her. She is quiet and keeps to herself most of the time.
Bio: She wasn't always a loner at first, she lived in a pride full of lions. She knew everyone's name, knew pretty much everyone. Most lions were male, so all the Lionesses got attention. Then a new male came into the pride, his name was Jakalu. He was a pure rouge at heart, he was also bigger in size then most of the males. The females in the pride were frightened of his arrival, and the males sensing their fear took their sides. Willing themselves to protect them at all costs, but the thing was, they protected all the lionesses but Kira. She was confused about this, and so was Jakalu, but this created an advantage for him. So he came closer to her, she took quick glances at the other lions, but they acted like she was a rouge too. This frightened her, giving off the scent of fear wafting throughout the pride. The rouge smelled it and she knew everyone could. As Jakulu got closer, he had a wicked grin on his face. Kira was posed to run, run out of their like she was a bullet just released from a gun. Jakulu crouched down toward her, his devilish eyes posed on her's. "Hello there, why are you all alone.." he said with a deathly stare, a stare that not many people or animals could easily imagine. She didn't dare look into those eyes that sent a shiver down her spine. He outstretched his paw, claws outseathed taking her face in his paws jerking it towards his. Her whole body bristled with fear, her fur standing on edge. She was about to unseath her claws, to take a good swipe across his gastly face. Then he came tumbling down on her, clawing her like she was his equal in battle. She cried out, but no one came to help. She thought she was done for, thinking that this was a punishment for something she didn't know she commited. She looked up into his eyes full of distaste, he smacked down hard on her head, making her dizzy enough to black out. When she woke up, the pride was gone, no scent in their wake to show her the way. The rouge's scent was gone too, only faint traces of other animals could she smell. She felt remorse, regret, humiliation and despair. All other feelings she keeps locked away, thinking that they were not the feelings she should ever feel or remember again.
Kira has found a new pride, but they don't aknowledge her one bit, they ignore her if she is close. And if she is father away they just do the same. She has a friend named Sukaya, but her friend has started to fall in love with a lion from another clan. Knowing her friend has found happiness is a great thing, but now Sukaya ignores her too. She wishes she could find another male, one that will stand up for her, protect her, and will always act like she is there.
