IBM Rational AppScan Enterprise Server – InstallShield Wizard

Hi,
The problem is with IBM Rational AppScan Enterprise Server setup.
I tried to install it and received an error message.
It stopped the configuration, as it was unable to login to the Jazz Team Server.
What does it mean?
How can I get a remedy of this issue?
Please help.
