Cannot complete action when trying to Activate Bug Tracking Modules

Question

I am trying to activate the Bug Tracking Modules feature on a site, and the error message is: Cannot Complete Action.
I have been able to Activate this feature earlier on my site and they still work.
I can activate the Bug Tracking List Instances, but not the modules.
I run WSS30/MOSS with service pack 1
Can anyone help me? - Thanks!
