Error while loading demo data

Hello All,
I just installed the trial copy of Tamino.
Did anybody tried to set up the TaminoDemo application?
I always got an error when I am trying to load data using schema provided with distribution and Tamino Interactive Interface.
The error generated is:
Bad Gateway
The proxy server received an invalid response from an upstream server.
Tamino Manager works just fine, creation of new dbase - fine, etc.
I am using Windows2000, Apache 3.12( came with XML starter kit ) and Tamino
Thanks in advance,
