c# - Hang while running 'hello world' test in Fitnesse -

I have our I am trying to evaluate Fitnesse for use with net projects. I am following the instructions of Gjko Ezik and fell on the first obstacles. When I run the Hello World Test on Page 1, fitness is just hanging on the running test screen

Is anyone else facing this problem?

How can I go about debugging issues like this?

I have solved the problem. It was wrong to define syntax COMMAND_PATTERN. I got% p on a different line
