jcbc test not working

Hi,

I am using SOAPUI 5.2.1 (not Pro) and I am trying to create JCBD test step.

In jdbc configuration like in the pic. Driver: com.microsoft.sqlserver.jdbc.SQLServerDriver and jdbc:sqlserver://xxxx:1435;databaseName=xxxx;integratedSecurity=true. I have used some SQL query in the window as well, which works ok in database manager.

jdbc conf

My database is Microsoft SQL Server 2012 (SP3), using Windows authentication. My system is Windows 8.1 Pro, Java version 1.8.0_77-b03.

I have downloaded MS JDBC drivers and installed sqljdbc42.jar into 

C:\Program Files\SmartBear\SoapUI-5.2.1\bin\ext and 

C:\Program Files\SmartBear\SoapUI-5.1.2\lib.  

Also sqljdbc_auth.dll (v64) is installed in

C:\Program Files\SmartBear\SoapUI-5.1.2\bin\ext\auth
C:\Program Files\SmartBear\SoapUI-5.2.1\bin\auth
C:\Program Files\SmartBear\SoapUI-5.1.2\bin

I have created the system CLASSPATH C:\Program Files\SmartBear\SoapUI-5.2.1\bin\ext\sqljdbc42.jar.

I get no message at all when pressing TestConnection in teststep window. Nothing. If I press teststep Play, I get message: 'Error getting response; null' in status bar. 

If I write OLD jdbc driver (for mssql server 2000): com.microsoft.jdbc.sqlserver.SQLServerDriver, I get an error:

com.eviware.soapui.support.SoapUIException: Failed to init connection for driver [com.microsoft.jdbc.sqlserver.SQLServerDriver], connectionString [jdbc:sqlserver://xxx:1435;databaseName=xxx;integratedSecurity=true]

I don't know anymore, how to proceed. My colleage is using SOAPUi 5.1.2 and similar works for him ok. I have tried both with 5.0.0. version of soap and 5.2.1. No success.
