Bigfish eCommerce Admin login failure

All,

I've recently installed the latest release of Bigfish Ofbiz eCommerce. Am
able to login to the Fashion House store front and Ofbiz/Webtools with no
problem, but no joy with the usual Admin/Ofbiz login for Bigfish eCommerce
Administration.

Error message: ". the information you provided is incomplete. You cannot
login to this application"

Any suggestions?

Thanks,

Chris
