Well, it's weekend and i want to scan things.
I open the David 3 USB STick and:
All exe's of the David 3 programm are gone. The David 2 exes are still there, but both (32bit and 64bit exes)of version 3 are not in the folder.
Doing a "Filesystemrepair" with Windows Tools shows some File000x.chk Files, so:
What can i do know, the software ist only 3 months old... .
