SOAP UI 4.6.4

I'm running free version of SOAPUI 4.6.4 to verify Retail application where it keeps failing due to using wrong user name and password.

I'm told that I need to use user name and password that I registered with SOAPUI, since it was free version, I don't remember I created one.

Here is what failing

<soapenv:Body>
<urn:RetailLogin soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
<credentials xsi:type="nam:credentials" xmlns:nam="http://localhost/retail/namespaces">
<!--You may enter the following 2 items in any order-->
<username xsi:type="xsd:string">mindful123</username>
<password xsi:type="xsd:string"></password>
</credentials>
</urn:RetailLogin>
</soapenv:Body>

Response

<ns1:RetailLoginResponse xmlns:ns1="urn:RetailApp">
<return xsi:type="tns:loginresponse">
<loginusername xsi:nil="true" xsi:type="xsd:string"/>
<sessionid xsi:nil="true" xsi:type="xsd:string"/>
<role xsi:nil="true" xsi:type="xsd:string"/>
<loginstatus xsi:type="xsd:string">Not able to login</loginstatus>
</return>
</ns1:RetailLoginResponse>

Please let me know if you have any solution or how to get proper user name or password
