Feral Heart

Hello.
So as you already know from the topic's subject, my FH does not work.
It's not a problem with logging in, nor entering the game itself (trying to get into a map/playing as a character). The whole application does not work and I really need to know how to fix it, as I'm in some active roleplays and can message them about this problem only in game. ;n; Think how I feel...and now make a brain storm how to get poor me out of this. ;3;
I've had this problem before. It stopped working right after I tried to export an object. I had no idea what was wrong, but everything was working correctly after I took the exported mesh out of the game (both from exports and my_objects). There's one thing that's different, though - the last time the game immediately crashed and didn't want to let me in again.
This time it also may be connected with exporting (this time a half-done map). As far as I can remember, I managed to export something (an object, if I'm not mistaken) after the last glitch and nothing really happened, so I thought I may do it again. Everything seemed to be fine, as the game didn't close. I don't know if that's important, but I forgot to close it before closing my computer.
I took everything connected with the map out of the FH file. .Object files, meshes, textures, terrain texture, the map file from media> terrains. But nothing happened. And that's what is so scary about the whole situation. ;o;
Restarting (both the computer and the game) didn't work. So maybe you'll find a good way to get me out of this...? C:

As it is said in the topic, I need some meshes to a post-apocalyptic map (two at all, one of them is going to be a city, so even normal buildings meshes welcomed!) and a battlefield. And simply some Sci-Fi meshes, they'd be also really useful. Thanks for help!
