Error message: "Sorry, but we can't obtain a license"
Hello all. I've been using CC on a corporate license which has just expired. Attempting to open apps following expiry of the license I see this pop-up:

I logged out of that account and logged back in with a different account (personal email, on a free trial initially which I plan to eventually upgrade).
Still seeing the error message. Have tried uninstalling/ reinstalling apps, restarting the computer, deleting certificates, and switching to a different user on the same machine - no luck.
However I can access the apps under my personal account through a different machine so I think the issue is with my computer. Is there anything I can do to make my machine completely 'forget' its previous association with the corporate license?
Any ideas much appreciated.
