Business Analytics: Configurator error


I have an issue. when I try to run the configurator,i get the following error
Create failed for JobStep ‘BA for MBS Navision’
If i click OK then it continues.
After the installation of advanced client when i run the configurator to upload the license,it fails at the first step itself.
Error is “Unhandled Exception.
Object reference not set to an instace of an object”
and the configurator closes.

Any suggetions to solve this issue?
