Transferring Titan one show

[Jarvis]

Help!

Trying to transfer a show from one tian one dongle/laptop to another and getting "An error occurred loading or saving the show: Titan failed to load the show"

The show came from a Titan one V9.0 and I am trying to load onto Titan one V9.1, is this the reason it won't load?

They should be forward compatible. Make sure the original show is a full save (not an autosave).

Still does it on fully saved show. ☹️
