Thank you Tanuj,
That seems to have sorted it and I have managed to export the jpeg's successfully. All the same I think I will roll back to 6.11 as dj_paige suggests till Adobe get a grip of this update.
Many, many thanks for your wise advice!
You are Welcome, Glad to help.
If I can't use my graphics processor, better go to Capture One... One of the worst upgrades from software history, ever...
