Unity3.1 window freeze!

*BTW THIS DID NOT FREEZE BEFORE ADDING ASSET: Default Resourses!(which i have removed!)*Can you please help? when i try to add a texture(or something like that..) like grass(hill) to terrain, the window freezes (the window with the tiles) i have uninstalled it and reinstalled it and still! the same thing happens! please help me!!!!

I'm going off your other question, you should update your graphic card... If this doesn't work, I suggest getting a new card... You can always go to 2.6, see if that fixes it. Have you tried opening up a demo project (Island perhaps?) and edit the terrain their? See if that works...
