Error when using Broken Delta Links Detector

I am trying to run the Broken Delta Links detector from the support platform. I get the following error:

Tue Nov 07 12:03:01 CET 2006 : java.lang.NullPointerException

Portal Version

• Value *****

7.0.8.0.0

J2EE version

• Value *****

7.00 PatchLevel SP 08

It seems like a required component is missing. Can anyone offer any advice?

Thanks

Andy
