Hi Jon,
Yes, I have done all that before.
I've manually checked for updates.
I've refreshed the CC app and rechecked for updates.
I've signed out and back in before.
I've renamed the OPM.db file.
Before all that I had completely uninstalled all Adobe CC apps, including the Creative Cloud app itself, rebooted, and reinstalled CC app and some others.
Same difference every time.
I'm now running a windows update, but it seems 'stuck' on the first about sql server 2014. Will let it go on (hopefully not for ever) and see what happens after that.
The above are all good suggestions, for which thanks to all.
But so far, no help, I'm afraid.
