Problem with box software

hi all

just recently im having issues with PRO software

up to now, any new version was installed itself after closing the program.

but now i cant open SamsungTool at all

its just stuck at splash screen with info that card not found, when box unplugged and plugged again it says "Program damaged"

what might be the issue here?? uninstalled and installed again but still same issue

Tried on another laptop, also got "no card error" message, but after unplug/plug i got it working and software updated to 24.6 and works fine
