Yes,by answering David's question (
yesterday) without explanation, we might rather think that it is the repair and the clean instalation that does not work.
Even if I think you want to talk about entering datas in display which still does not work (with the English UI)
However , you only said yesterday:
I uninstalled avast, reinstalled, and still can not enter the account data.
What you have done here
is not a repair -> did you tried ?
Nor it is a clean instal -> so , also try it if repair doesn't work at first.
It is now that you have tried with the English UI certainly more the solution than a Polish UI display issue , I think ?
