recording technique practising

Hi there, well, I did not pass my first exam thereby my next exam have been re set for tomorrow. I decided to reserve a studio for practising. Although, I set up everything properly, I was not able to get signal in to the computer. I tried almost everything to solve the problem. However, nothing worked.
