Don't worry, crashing the Fluorite is really common and your graphics card shouldn't be a real problem. Try to wait it out, and if it doesn't work, change your Render System by going to c: > FeralHeart > ogre.cfg
After you get there, you should see a line saying
Render System=OpenGL Rendering Subsystem
[OpenGL Rendering Subsystem]
Replace OpenGL with Direct3D9 and go in-game.
HOWEVER, if that doesn't work either, it may be a server problem so I suggest waiting for Feral Heart to calm down.
