Thanks for your answer. I am in contact with Michal from open-e support.
I was recommended to update as u said to latest version.
So far i updated from version 3084 to version 3278
Now i want to update from 3278 to b4562 but i am not sure if it sure that i wont loose my data.
so much warnings in the readme :-(
The Readme says its recommended to update to b4562 trial version.
Is it really so much risk to directly update to b4562 without trial?
I know strange question, but i have to get rid off before mentioned problem quick
