Well, once the server is back up, you'll probably have an easier time with the game.
What you could try, though, is changing your rendering mode.
To do this, go to your FeralHeart folder, and open the ogre.cfg file with Notepad. Then, change the very first line to Render System=Direct3D9 Rendering Subsystem.
When you've done this, hit save, and then exit the window. When the server is back up, try opening FH, and see if it works any better for you.
