I'm new on Blender and watching all the tutorials I can.
One of those tutorials recommended some changes on User Preferences and every time I try to open it, Blender stops working and shuts down with no further information.
I'm running Windows 7 32 bits with SP1 installed.
Thanks in advance
P.S. I already tried to re-install Blender and this problem persists.
Video driver problems.
Try changing the window type to the user prefs space rather than going thru the file menu.
