When press Test Request nothing happens

Hi,
I started tutorial https://www.katalon.com/resources-center/tutorials/create-first-api-test-katalon-studio/ and after I’ve created the Request in Object Repository in Katalon ( I used Get Method from this API https://market.mashape.com/andruxnet/random-famous-quotes ) I click the Test Request in the menu. After that nothing happens (no response, no errors). Can you provide what am I doing wrong or can you provide me information does this functionality work at all?
Thank you, Viktor
