We have a Mitel 3300 switch and about 60 extensions.  I am tring to roll out Your Assistant V3.03 and i am having extreme dificulties.  The server aplication installed OK, all the services are running and it is correctly licensed.  I can add users to the server OK and when i add a user it correctly changes alocates 1 seat and the user apears in the licensed users section.  However i cannot get the client aplication to work at all.  I have installed it on two PCs which both fail to work in different ways.  

The first one gets as far as the "handle calls using" dialog, when i select deskphone (the only option available as i do not have any softphone licenses) i then proceeds as far as Initialising Call Frawrding Policies and i then get the following error

System.NullReferenceException: Object reference not set to an instance of an object.
   at NewHeights.BootStrapper.BootManager.Boot()
   at NewHeights.YA3.MainClass.Init(NameValueCollection yaSettings)

This happens even if i tick the work offline box.

On the second PC it only gets as far as attempting to license user domain/username when it gives me the following error

Initialization Error

Your Assistant is unable to connect to the Your Assistant Server. The server address given was 192.168.1.5 on port 2114 and may be incorrect. Please contact your system administrator.

I have done a port scan and the PC in question and i can see port 2114 on the server 192.168.1.5 and it is open and it is the correct server that YA is running on.

Can anyone shed any light on these problems as the mitel site is pretty much useless.
