Having issues (similar to XCalibur on May 3rd). I purchased WeatherFlow from the store. When I go to install it, the installation flow never gets me to a place where I can pick a slot and install. I've tried rebooting twice, which seemed to fix things in the other thread, without any success. 

Here's what the flow looks like for me:

I select (Re)install, that brings up the following:

When I select update, I simply get a "Cancel" button in the UI.

You should update to the latest version of PG3 as this issue has been fixed.

The (Re)Install button isn't really correct.  It should be labeled "Update" and you can only update if you already have it installed. 

Instead, go to the Node Server Store, select the node node server from the list and then click the "Install" button to install.

This resolved it. I had just upgraded to 3.1.26 about 10 days ago when I installed my eisy and had that in my notes. I should checked for an update before posting. Thanks for your help.
