PAY MODE FAIL

This afternoon I downloaded the latest pro program update. 11.1.2253
I can not get PAY MODE to work it says SOMETHING WENT WRONG and to try again and then gives suggestions.
I have shut down and tried again twice with no success.
(I have also noticed my changes to an UK English dictionary are not holding.)
The only way I can get into my bank is not to use the safe browser.
Thanks

Perform a repair of avast.
If that doesn’t solve it, perform a clean installation of the latest version.

If I do a clean install does it pick up the licence automatically.?

No, you will need to use your license file.
You can get it through your account > https://my.avast.com
or
