Look, chill out with posting a thread every time you can't do something.

You need to be patient and LEARN how to do stuff.

LEARN = READ+PRACTICE

If you are a beginner, which it sounds like, post in the 'Getting Started' forum not here.

Nobody here is going to tell you how to SET UP YOUR STUDIO PROPERLY!!!
