Unable to connect to SQL server

Hi @Rocko/All

I got this block-

https://community.ptc.com/t5/Vuforia-Studio/Easiest-way-to-connect-an-SQL-database-to-Thingworx-Studio-For/td-p/529820

where there is one link to get the extension for JDBC(SQL SERVER) -  https://marketplace.thingworx.com/tools/jdbc-connector-extension is not working can anybody point me to right link?

Also, I put the JDBC driver(main one not the extension) in tomcat/lib and trying to  connect to MSSQL server by using a Database thing but not able to connect. any idea, am i doing right?

Here is the log: 

[context: com.thingworx.webservices.context.HttpExecutionContext@7504795c][message: Thing [MSSQLConnection] is not running]

Thanks!
