Ferret Demo application - failed

Hi all,

I decided to try the demo project that comes with the Ferret plugin and
following the instructions in the README_DEMO file faced this problem.

I guess it is luck of experience but I could not solve this problem.
Any ideas are welcome.
Thank you in advance.

Regards
Chudomir
