I have a set of ActivExpressions v1 that I just upgraded. I first upgraded the kernel from 1 to 2 and then then to the current build. Now none of them will register to the hub. I keep getting a message that says their is no active registration session open. What should I do?
Have you also updated your Hub and Driver? You shouldn’t normally have to , but in this case I would recommend getting everything on the latest version. You can find the latest ActivDriver and Hub upgrade instructions on our Knowledge Base, separate links below:
