Problem connecting to Instance of SAP Business Warehouse 7.4 SP5 incl. SAP Business Objects BI 4.1 SP2 on SAP HANA 1.0 SP7

I am attempting to set up SAP HANA trial.

Created instance as above, apparently OK, but when I try to connect via either the Connect button or using Remote Desktop and the IP address directly using administrator / Welcome! (from pdf "Exploring SAP Netweaver BW on SAP HANA...") I get the response "your credentials did not work"

Any ideas?
