Softube Flow suites not loading after restart

Whenever I open a project with any of the Softube Flow suites loaded, everything loads fine.

But when I reopen the same project while the hub is still open, I get a warning that the flow suites are not found in any channels that they were inserted in. If I open a different project, that opens with out a problem.

If I close the HUB and open the previously opened project then it opens without a problem.

Softube havn’t been able to figutre this out so I thought I’d give you lot a go. It’s not a huge problem, I just need to remember to close the HUB before restarting any project. I don’t know if this is a Cubase, Softube or windows problem.

Thanks for any help.
