Version 4 doesn't work .. Want refund and revert to 3

Enhancing runs for 15 mins and does not save your edit. Both a suggested 1.5 and 3x
I was very happy with 3 but did update and did not realize I was buying a new version for $73.00 a real ripoff

Don’t complain here, we are all users so we cannot give you a refund. You will need to raise a support request at the main website.

BUT if you are experiencing problems saving while using as a plugin, turn Upscale off either on the panel or in the Autopilot preferences.

This was fixed in v1.4.1. Please update to the latest version and this should be working again.
