Exploratory Regression Tool error

Just to see if someone has gone into this situation. I???m using the Exploratory Regression Tool and it suddenly quits showing the following error:

AttributeError: 'module' object has no attribute 'readWeightsHeader'

At first I thought it was an error with the layers i'm working, but I tried with the layers provided in the 911 example tutorial and the result is similar.
