Mission "Resurrection" accomplished
On my old laptop with Win Xp, 32bit I installed old version eBook Library which lead to install the correct drivers. After opening the soft said that Reader has error, however the underline information for me was that it was connected. Then I run the PRS-500 Updater 1.0.03.07170.exe and after finishing was my PRS-500 resurrected.
Thanx for all help with this.
Now I can focus back to the reason why I ruined it down with PRScustomiser - I'm slovak, and the special characters of central europe are not shown correctly. So I go to work on that again ... maybe the update already solved that - I need to check ...
Thanx again for help.
