Just a posting for info in case it help others.
My off the boat/backup computer is a Mac. I use VMWare to run a virtual Win10 environment for Exp. I recently updated the Mac to OSX 10.14.2 Mojave and found when I started the VM that the mouse and keyboard weren't being passed to the VM - you could see it but not interact. I was running VMWare v8. The short version of the story was that on updating to VMWare 11 ($50USD upgrade) all now works again. I needed a new Exp key, which Nick delivered with his usual efficiency, and all now works once more.

We run a similar configuration on our boat. The main computer uses boot camp on a Mac, and my backup is a MacBook Pro running Paralelles. I have occasionally run into similar situations, and am always impressed at Nick's response time on those occasions when I need a key. I appreciate the great service!
