--- Comment #40 from Sebastian Lackner sebastian@fds-team.de --- Ah, thanks - I expected that there would also be some visible output on the terminal, the download of this file was so fast, that I didn't notice it. ;)
I can confirm that it redownloads the executable each time when validating the demo, here is an example diff: http://ix.io/dU5 .
In the meantime I've also tested with the Mafia II demo, but same result as always: CEG executable, but works well in Wine...
