HP t430 rdp file won't connect to remote machine

Hi! I hope someone can help me with a problem I'm having. I've got a new t430 and it seems really good. I'm trying to pair it with Azure Lab Services. Azure Lab Services spins up a VM for X number of people and in the web page you get a download link which is a standard RDP file. What I thought would be a simply case of clicking on the rdp file and launching that connection on the ThinPro has turned into a nightmare. The RDP Client works if I manually enter the details for the RDP however using the RDP file I get his error appear.

in the above, it appears to me for some reason it thinks the host name is blank and the port number is the standard port (it isn't). I'm running the latest version of ThinPro and the latest version of FreeRDP which is 1.1.1-hp16.3. Has anyone here encountered this issue before and can offer any advice on how I might resolve it. Apologies for not providing more information but my knowledge of linux based systems is pretty low so if you can explain what you might need Ill send across anything else to help diagnose the problem.

Best Regards

Richard
