If you see this screen when start Etka

it means, you need to update Etka database!
How to do it?
it’s simple, on Desktop you should have Automatic Updates folder

Go inside and you’ll see:

Data – main etka database update
Prices. – it updating prices.
Just simple run Data

and click Search updates, it will download and install new database. It will take a while so do not cancel or stop that process.
After it complete, you can start main Etka and should works fine now.
Still doesn’t work. mine just keeps telling me to go to 8.6
