Trouble connecting to mongo

Hi,

New to PDR.

I am trying to connect to mongo db using PDR 5.0. I have the mongo-java-driver-2.11.3.jar in the \report-designer\lib directory but I still get the error 'Unable to retrieve database names' when I try to get a list of databases.

I restarted the app after I installed to driver and I definatly have the correct user/pw.

Any ideas? Do I have to set a path?

Thanks,
