when you google for the first line of the error you get:

http://www.mathworks.com/support/solutions/en/data/1-IMBXXS

You followed it which is good. The warning about the duplicate entry can be ignored (its a known problem).

So make sure you pathdef.m file exists and has the expected content. How to do this is explained in the link above.
