Matlab not working.What to do?

I get an error when I'm opening Matlab

Warning: Initializing MATLAB Graphics failed.

This indicates a potentially serious problem in your MATLAB setup, which should be resolved as soon as possible. Error detected was:

MATLAB:structRefFromNonStruct

Dot indexing is not supported for variables of this type.

> In hgrc (line 151)

In matlab.graphics.internal.initialize (line 15)
