Thanks so much Alan - I may be telling folks what they already know; After installing this new version, I still had the same symptoms - i.e. it looked like it was connecting, but would just hang. I noticed that in the folder you sent it had a file called 'clear preferences' and so I did that. It meant I had to create a new studio in MXView, and re-enter the IP addresses for my 3 machines, BUT it worked!
