I forgot to mention: I run windows XP professional.
Tried some other experiments:
- BS disinstall, PC restart, registry cleaning, PC restart, BS install => Same result: white screen and error message
- Launched via command line: "C:\Programmi\Eagle Dynamics\Ka-50\bin\stable\Launcher.exe" (same as the desktop link, but without "--console"). I obtained the following error: "cannot open.\BlackShark\BlackShark.lua : No such file or directory". No white screen or other messages.
I checked and BlackShark.lua is present in C:\Programmi\Eagle Dynamics\Ka-50\BlackShark directory.
I red many thread relevant to Launcher problems, I hope the developers are working on this issue for a fix in the next patch..
