The NDS3.0 which I installed can't run rightly.
The UI Designer module's state is always error,when I run the NDS.
And a message " null"
is shown in the General Tab.

However,There isn't any problem in my classmate's computer.
The UI Designer's state is OK in his NDS.
His OS is Win xp sp1 english edtion.
My OS is Win xp sp2 chinese edtion.
what can I do?
